I've been mulling about this... and I have to say... I'm concerned.
What will Sorcerors be like at level 20?
Currently... Sorcerors can kill with a word, charm constantly, raise the dead, heal like mad, and lob damage spells left and right, and can come equipped with more than a few rather useful buffs.
I've seen Sorcs cure blindness, disease, paralysis. I've seen Sorcs raise the dead. I've seen Sorcs wand heal very very well... and in some ways, I've seen Sorcs... well... Tank.
Yeah, Sorcs can... in a backhanded way, tank.
When a Sorceror charms five guys... that's what he's doing. He's tanking.
He's keeping the aggro off the team. Sure, it can be considered crowd control, but isn't tanking just another form thereof?
So, one must ask... where does it end? The immense power of the Sorceror...
At level 20 a Sorceror will be able to (most likely, if the Devs give them the iconic spell) walk into a room and kill everything in it with a single spell. What's worse they will be able to fire this spell off repetitively. A level 9 spell will only cost 50 sp. How much SP will a level 20 Sorc have? A few thousand? Most likely.
What's going to happen when Sorcs ascend to virtual godhood at level 20?
