In that other discussion, the comclusion is looking like a player should be able to self sustain at the cost of losing dps. Also damage shields need change for less op functionality.
In your OP, you haven't really given us a lot of information to work with. The most I can produce is pure speculation. I'd say that infinite resources is completely fine as long as the player in question is not unkillable and destroying everybody at the same time. One or the other is fine.
