You're putting words in my mouth if you think I said casters and/or Melee are OP. I've said multiple times already that I feel the Adrenaline system could uses balancing. I honestly thing people mistakenly undervalue Melee in Slaughter as they're quite effective if you take advantage of their strengths and use them to apply pressure to opposing teams. Every single one of them has a gap closer that can be used to snipe down a squishy with the appropriate co-ordination. Players just don't coordinate as easily when they're not premade groups.
Also, this sounds a lot like personal bias on your end - meaning you, personally, are having troubles against melee. Your profile says you only have White Mage leveled. Are you PvPing on an alternate character as a DPS Mage, if so... step down from the horse a second and do some research. Lots of guidelines, especially for BLM, on how to take down a Melee one on one. Talk to your peers on how they handle the situation.
And again, this is all standing on an invalid straw-man argument that each class should be equivalent to each other in a team game. That's just not a reality of team based PvP. I don't know how this escapes you. A lone healer gets dropped on by a melee and ganked, that lone mage was out of position to begin with. To be truthful, no class should really be alone in these modes.
I'm seriously tempted to get on my Arcanist character and push to address your concerns from direct and recent experience. However I've more pressing reasons why I need to focus my PvP efforts on Hyrist right now.
I can see some of the logic on the Beta Drone, but I can’t entirely agree, I’ll explain some of my logic here.
The reason why Beta Drone dies before groups return is usually an error on behalf of the ‘Center’ team for the objective focused team. If they are DPSing the node, they’re giving their team less time to come up.
What they should be doing at that time is playing interference for the other teams - making it as painful to focus the Beta Drone as possible. I’ve recently had a team successfully pull of this tactic and enable their teams return to secure both an Alpha and a Beta Drone. (Sadly, we lost the Node after and that kinda negated our lead, but it secured us second.)
I could see perhaps a 15-30 second delay, but having multiple valuable objectives on the field does ask for a split focus, which I feel is good for gameplay overall.
Still, the Meta is new. I’m wondering how long the BLM trend will continue once melee’s realize that it’s easy to rush + Fetter Ward Raw Destruction most mages dead straight out. Nowadays I mostly see Melee trying to use it to capture objectives, which, honestly, I think Cometetor does a better job at it clears enemies away from the target as well.
