Introduce a Mini-Selentine Golem in the Yellow Zone
Add mini-selentine golem to yellow zone. Half the size, half the loot, slightly weaker.
Blue/Yellow zone players need MORE, not less content. Vets going to the previous sele with infernal was an issue, but now they'll at least take an efficiency loss by going to the mini.
Can also have a plan to give yellow zone a mini veilron and neithal golem at some point down the line, something like 1-2 months from now? Then once 64bit comes out you'll remove it for launch and re-add them 3-6 months after launch?
