This should help the lower level players a lot with selling and buying items / materials.
In my opinion, giving everyone 200K for free is a bad choice, even more if this is for every character instead of per account. (people might create 20 new accounts with a day or week subscription, meaning 100 chars & 20.000K for real money which isn't a good thing for Wakfu).
Like said before, it is a nicer thought that all kamas in game were created by players.
Bosses dropping kamas, I'm not sure about this yet. How Resonate it said sounded nice for the low level players but this could give high level players tons and tons of kamas per dungeon run which they will do anyway because they want certain drops (plus the drops can usually already be sold for pretty high prices).
When the higher level kama recipes come out this might not be so much anymore when you compare it with the time you could spend mining against the time it would take to run a dungeon but that is for later.
