Do you rly think that all that mages do is use magic for "creating devastating spells" DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD?
srsly? and that mages doesn't use reagents for their spells? More powerful spells requires reagents as well.
and mages aren't guys who spent 90% of their life fighting. Most of them doesn't use 5% of their life fighting. Most of time they just stay in home and create portals, enchant items and create magic items, elixirs. Lorewise Warriors are those who fight and mages fight only when they have to or are hired.
don't take gameplay so serious.
