Please consider removing the level locks for BS's and changing the mech mechanics. As things currently are it's impossible to get some BS action at most level ranges.
Ideally the new level limit for entering the BS would be level 25, and everyone from level 25 to 175ish who entered the BS would be in a mech at all times, chosen when they entered the BS. Further the mech-roles they can fill would vary by profession and would not be available to players 210+.
The roles would be Support unit, Artillery unit, Control unit, and Infantry unit (original huh?)
The support mechs would be able to heal players and other mechs and be able to cast a dot that ticks for 1K, 4 times every 5 seconds (20 second recharge)
The Artillery would give very large but very short lasting Ranged init buffs, evade buffs and damage buffs in addition to having one attack that lowers health by 20%.
The Infantry unit would offer substantial hp, ar, and damage buffs (also very short term) and one attack that lowers health by 20% and
The control unit would be able to cast roots, snares, and aad and aao debuffs and one attack that lowers health by 20%.
All of the basic support mechs would have the same defense/offense/hp/ar regardless of the level/equip of the character who's in the mech.
At 175 players would be able to access the current attack mechs and fullfill those roles, maybe those can be expanded to be more effective, I'd like to see some opportunistic attacks that only worked when hp was above or below a certain percentage.
At 210 players would be able to walk around the battlestations in their current gear.
The BS's would only start once each side had an equal number of people 10-20, and there would be a certain number of support (25-175), mech attackers (175-210) and normal player slots alloted in each team to ensure balance. Maybe 6 support, 6 mech attackers and 8 players.
The level ranges are of course maliable but I think this would be far better than the current system. A setup like this would allow everyone to participate and would encourage lower level players to learn teamwork/support and for higher level players to try and work with supporting players. Plus a system like this would ensure consistent access to VP for all and consistently running BS's. And guilds can participate jointly in BS's without having to worry about having enough people of the right level.
A bonus is that it creates a VP sink, players can buy access to the different mechs, mech abilities and have much more mech stuff to research.
