While we'll have to see how it functions in action before jumping to conclusions, battle high changes will probably result in more battle high across the board, especially among jobs that didn't have strong kill potential. This change is going to effect solo queuers and teams playing catch-up more than premades, I suspect. I personally look forward to not having to prioritize killing blows as much.

I'm really looking forward to role actions: more diversity of options in PvP is always a good thing.
