I'm extremely skeptical about this change. For example always every single sith raid I get a fully or partially crafted piece. If they change the rewards to be even between members, that'll mean we get less, and plain garbage, just like the Pit/ATT Raid when skimmed. The medium line rewards which are not exactly a motivating factor at all. I guess we'll have to wait and see but knowing CG's track record I'm not holding my breath on this having a positive impact.
Also, having raids that are team specific is going to cause issues again. CG says "they don't want Guild members to compete against each other" this will cause a lot of guilds to fall apart. As most Guilds will mandate at least one of those teams. We already have character specific stuff in TBs why do we need to implement that in Raids as well? Doesn't make much sense at all.
