I came back to DDO recently after a 2 year break. My main (only) character at that time was a Wiz 14/Rog 2. Trying to get him to 20 now for a TR and....I'm hating playing him :/
Maybe at one point I had the knack of budgeting SPs, but I don;'t seem to have it now. I'm eating DDO store SP potions like they're going out of fashion. Could be a problem with my enhancements and/or gear (it's junk), but the character feels....meh.
On the other hand, I love love love the rogue splash. I mainly solo (no choice, small child) and I can get through most quests with this char.
For my TR, I'm liking the look of Sorc, but I dunno if I can live without Rogue splashes, and I just can't see how it'd work.
