You say "any melee boost they give them will not be enough to "fix" any problems they already had", but you can't even tell us what that "problem" is. I'll tell you the most important problems about RDM and WHM melee.
The first issue about RDM and WHM melee is the "buff cycle" as people call it, or in another word they are busy. That is the first issue. If we can't get agree on that part, we're not playing the same game. Conclusion, we need to lower the number of casting to help them.
Secondly it's the accuracy, like I said early, from that interview, we can expect an enhancement on the RDM attack skill. Those are the 2 main problems about the melee subject.
Some people have mentionned refreshga and hastega in the past for that reason.(They are busy). The goal by making beneficial status from striking is to lower their number of casting.
