(sorry for mistakes in english, it is not my natural language)
It is my build, currently at lvl 22.
I've always envied selfhealing ability of Warforged race. Warforged race is unavailable for F2P. Later, i've found magic of dragonmarks. So i tried to build pure sorcerer based on dragonmarks of healing.
First life, first character (no shared gear available)

Starting stats (28 pts)
STR: 7 (-2) - put 1pt to boost little STR to get better protection against STR damage at low levels
DEX: 10 (0)
CON: 16 (+3) - it is better to start with +3 CON
INT: 12 (+1) - need 3 skill pts
WIS: 8 (-1)
CHA: 17 (+3) - you can start with 18, but you will suffer 2pts on CON and 1pt to STR
Boost CHA at every 4th level
Concentration, Diplomacy, UMD. Leave a few points on tumble.
Diplomacy is your armor, keep one finger above the hotkey during battle.
1. Least Dragonmark of Healing
I am taking this for first level, because there is no feat more valuable at this level for this build. You gain 3 times of Cure Light Wounds, which can be extended to four using enhancements. You can also cast CLW on friend. This can sometime help in parties without healer.
3. Maximize spell
You will need one of these metamagics (Max or Empw) for PrE, so take Maximize. Use feat to empower your dragonmark! This will not cost any SP, so there is no reason to have turned off this feat for dragonmarks. Keep turned on. Your dragonmark gives you twice more HPs now!
6. Lesser Dragonmark of Healing
It gives you two Cure Serious Wounds and adds extra usage on CLW. With enhancements, you will able to cast 5 times CLW and 3 times CSW. Don't forget to apply maximize feat!.
9. Evocation focus.
You will need this for PrE, don't need to wait
You will be useless without this at highter levels. Don't take Greater dragonmark, there are more important feats. If you will have a luck, you can win Bottomless Flask of Rum Tier 10 during Crystal Cove festival as alternative to the greater dragonmark.
15. Spell Penetration
Must have this feat
Some leaders want to check your HPs at higher levels. (Foolish leaders doesn't know, that you can heal yourself. Try to spend some letters for description of your toon into "bio" field. A few leaders can read this and there is small chance, that they will not kick you from the party)
21. Greater Spell Penetration.
Helps in epic
Air Savant I/II/III, Spell Penetration, All dragonmarks, All racial toughness, Sorcerer charisma +1, some EofD.
Sonic Blast (very usefull, I am still using this at epic levels as "basic damage" when other spells are unavailable due cooldown)
Magic Missile / Force missile (some mobs are immune to eletric/sonic spells. Shroud portals from phase 1 can be hit by only Force missile. Similar to some monsters from demonweb)
Some AoE spells from Fire or Water element (firewall, Ice storm), because Air savant has lack of classic AoE spells
Shocking grasp, Electric Loop, Lighting Bold - Use Air savant spell-like ability!!. Apply Maximize and Heighten (it will boost eletric loop's daze efect, tanks will love you!). This doesn't cost any additional SPs!
Cyclonic Blast (heighten), Eladar's Electric Surge (Maximized) - BOSS KILLER - apply Awaken Elemental Weakness after use EES.
Set of must-have spells: Shield, Blur, Displacement, GH, Resistances, element.protections (buff both, resists and protections), stone skin, rage, false life, expeditious retreat, jump,fire shield.
Energy Drain, any kill spell, Disintegrate, Banishment, Dimension Doors, Prismatic spray,
Staff is your only weapon. Boost spell power for air/sonic spells. Replace your staff on every level to achieve better spell power enhancement. Check AH, try to find staff with magnetism and resonance and/or with lighting or sonic lore. Also keep potency highest possible, it will boost your dragonmarks. You can have one item to boost positive spell power or craft items with alchemical power clicky
Gauntlets of purple dragon - boosts your healing +30%. At epic levels, your healing is less effective, so try to get this item as soon as you reach epic level.
Craft Ring of persuasion to gain +3 to UMD and +3 Diplomacy
Boost SPs (Power, Wizardy, Archmagi items).
Heavy fortification, Deathblock, spell focus items, avoid arcane failure, wear only robes or outfits. On other side, inherent spells are not subject of arcane failure! so you can benefit from light armor sometime.
Result: You will forget how to buy hireling contracts. Most of heroic quests can be soloed on normal or on hard. In parties, your life no longer depend on healer's reaction (healer will first heal tank-meles, casters are lower at his priority list). After you are hit for alot HPs, you will able heal self faster then any healer including hireling.
