ROE bonus should change? (in General)

Now from what i can remember... the roe adds 20% additional experience for a single minion right?

and it does different things for multiple minion teams...we all get the point...

however...with the new changing of the ncb...427%...when i put the roe on will it be "in theory" 447%...so 20% of the 427%...

or 512%...

Also...if it is indeed only 447...do you think roe should be a tiny kick in the pants?

like maybe 40% since the ncb bonus just jumped (almost doubled) AND amount of BA one can buy went down to 1/3 instead of 1/2?

Doesn't really do it much differently on multiple minion teams.
2 minion will get 40% more XP than they naturally would on the wearer. End reward 50% +(50%*1.4) = 120%.
3 minion teams with a RoE user will get 60% more XP than they naturally would on the wearer. End reward 33.3%+33.3%+(33.3%*1.6) = 120%
4 minion teams with a RoE user will get 80% more XP than they naturally would on the wearer. End reward 25% +25%+25%+(25%*1.8)=120%

20% is more than enough though ^_^

RoE bonus is multiplicative. It claims to give the XP that it would earn to the wearer, which is affected by N*Bs.
