Eating my karma?

I like the game but I am having some issue getting past the fact everything but weapons and healing needs KARMA which seems to only be gained by leveling up. Then if a ninja dies in battle not if you loose just an individual ninja lost it goes down in level . It costs a karma to level up and some weapons can only be wielded by a specific level it costs like 8 karma to level your buildings up after level 6. karma is way to rare to penalize level for it even if this is abusing the pay to win strategy. If your level only went down when you lost to players ok fine you loose money and exp makes sense but loosing to the tough npc you loose just EXP its free but thats not cool I just get weaker and I see no point in grinding in lower levels because you get no gold or karma I dont even know if you get player exp for it . The achievements need to give more then 1 karma because when I got it I either cant build that upgrade so my dojo can hold hire level ninja or I dont want to level up a ninja because they keep loosing
The game is fun but has a serious issue with Karma please fix this
