what is the purpose of having a cost for favor items?
- to seperate the noobs from the pros? the losers from the winners?
- delaying the purchase of the most viable favor items available?
I think this game is all about balance (as are many games now). All favor items need to be roughly equal in strength.
If everything were balanced, it would add great diversity to character builds and unique playstyles without having anyone on the arena have an advantage over you.
Of course this would render the favor point reward (at the end of a match) as useless because you wouldnt need to "buy" your favor items anymore, but i think this would a well worth sacrifice to make the game more balanced.
