For certain bosses what are the reccomended resistances? My guild is looking at starting SSC and I'm currently the MT (druid 4/5 T4 with various other epics) and I'll probably end up tanking the corruption phase of hydross (as I'm tauren with the racial bonus of +10 nature resist). Should I gimp my gear by trying to break 200 Nature resist unbuffed? Or can I get away with just replacing my rings and maybe 1-2 pieces of gear to get like 100-110 resist unbuffed?
Also, if there are any other bosses in SSC/TK that require resistance gear what should I be shooting for with them?
