you cant do that with exalted warrior, you cant do that with exalted tank, barely with archer, not with wizard....a played should be able to play whatever they want, and not limited to a summoner
also, runestones are over priced because they removed ways of obtaining runestones...your harmony level 2 buff costs you 8 runestones which is currently over 1billion adena on either server...better to wait until next update for runestone skills
better idea is to remove runestones, or any skill requiring monetary investment....back in the day we purchased skills with skill points and spellbooks, and we could farm spellbooks
we cant farm runestones, unless you run balok/istina on low level toons...which causes you to create low level toons for farm or keep your dualclass low level, just another example of how this game is in very bad condition
