Still, I don't really bother with Tor anymore. Y'know, due to power creep, shadowfail is better to play. :)
Honestly the only fool I see here is someone who is making statements without any experience to back them up. Melee Sorcerer is not the most ideal build but it certainly is very doable and has been for a long time. Epic Destinies further added the ability to deal acceptable damage.
So if you chain cleaves into your attack animation routine when surrounded(Or near) a large number of mobs all the other mobs take damage while you focus on one. This gains you DPS, and saves you time because when you move on from one mob to the next, each consecutive mob has less and less HP than the one before. So where the first mob may have taken 6 attacks to kill, the last one may only take 1 attack, or may simply die before you ever get to it.
What you're saying has merit on paper, but in actual play things aren't so simple.
+1[W]/+2[W] =/= regular attack animation for single target DPS.
+1[W]/+2[W] > regular attack chain animation for AOE DPS.
AOE DPS > single target DPS 90% of the time.
Think of it this way, your regular attack animation allows you to attack and damage 1 target at a time.
Cleaves, while making you lose DPS on that one target allow you to get a single attack off on each mob around you.
1 Attack on one mob =/= 1 Attack on several mobs DPS wise.
This also means that if you're using any sort of CC weapon, like paralyzing for instance, that when you cleave that has a chance to apply to all the enemies around you. Against the right mobs this effectively gives you as good CC as a dancing ball would. Something a Melee Caster usually lacks is reliable CC because the lack of both Spell DC's and the lack of tactical Feat DC's. This doesn't close that gap entirely, but it helps to some extent.
