i would go with (A) for samadhi and nirvana shouldnt be a chance, it should just summon a random dead ally. But i personally would add a twist to that, and have that summoned teammate start loosing 2 dmg/s after a minute? this gives enough time (2 minutes almost, the optimate time for a round) to complete objectives and kill ppl, but not enough to have someone just camping and summoning people... Not sure about what ppl think about kdr, but skilled players should find a way to finish the round before the whole countdown ends and their health depleated...adds more suspense to this game
