Due to their capacity to heal with magic, Toasters / Lego men have come to dominate magic in DDO.
This, imho, is bad for a variety of reasons.
1. Lore. It is not brought up often, but I think a large number of players choose DDO over other MMORPG because it is loyal to its D&D inspiration.
Warforged are NOT meant to be wizards, but fighters.
2. Balance. Arcane casters have the best offensive capacity of the game. Balance comes from the fact that they are NOT as resilient as fighters or divine casters (and of course SP management, but this is another matter). A Toaster is a selfish cleric and an arcane at the same time and this breaks balance.
I am aware that some players will shout that there are enough nerfs coming our way as it is, or that they find it funny to have a caster robot, or that they have already invested a lot of time in their Toasters of Vengeance. To me, those are not valid reasons to keep something that doesn't work on the two most important fronts of the game: balance and lore. Compensations could be handed to mitigate the pain of the adjustment.
