I don't really see your point. For example if recklessness were to stay, how would a balance druid feel in a 10 man raid that didn't have a warrior on their roster? It's exactly what's happening with dark intent right now. A shadow priest without dark intent is practically fodder in a PvE environment. The same goes for a warlock that doesn't have a class that can provide the optimum amount of dark intent stack uptime.
What I would like to see (and seems to be happening) is that these are entirely utility based. So let's say on a certain encounter a given druid is having trouble with moving out of a mechanic in time. That druid can choose from the variety of classes in the raid what type of ability to obtain without hurting the raid's total output (damage or healing).
My point is I want the choice to be on the DRUID. If DPS or HPS becomes involved, then regardless of what anyone says, it'll be some spreadsheet that will determine where symbiosis goes, and not the druid.
