I prefer MTS rates and style of gameplay over Mesa and INX before y'all start talking about it. I'm older and most of my hours are on MTS and Smalls.
However, they had a great idea with the Element Arenas. It increase PvP and provides a way to foot fight over Ele other than just spamming Bosses, Waiting for the occasional Gen2, or doing the stupid liquid Ele thing on Abb. Every 10 ele of shards weighs 50. Most people have 600-800+ weight on their characters at lvl 105 with 20 per pump which will only increase as wipe goes on. Carry 20 ele per person, its a 6 man server. Weighs just enough to be burdensome but not enough to prevent you from having a good kit. Worth it to go but not OP.
I think an MTS PvP arena with Ele Crystals in it would be fun and in addition promote clips, which is free advertisement for the server.
