its a point of no return, they spammed game with EMPs, guided weapons and whats not, you cant reverse it back. Mechs purchased money paid. I agree to some people who are saying you are now being in frozen state under some EMP effect from 100 directions half of the battle.. its not a shooter like Cod anymore, its a different game.
To remedy the mess they could create a separate battle mode with just common, rare and uncommon mechs.. and actually add more of such mechs like something proper basic as wall climing etc, instead of trying to make a new super strong frankenstein that freezes the time to kill everyone around with one sight traveling into matrix armaggedon.
As for how to deal with Volti with common mechs, even i am sceptical :) you just die. Whether its an issue or a feature i dont even know :) you can beat any legendary with common,rare etc but not Volti hahahaha
As for your orion, you will not like to hear me.. i played about 5 months and i have Salvor, Dreadnought, Vortex, Solis, Hemlock, Outlaw and Bastion.. And just a month ago i barely had any legendary mechs at all. If you spent a year and still dont have good mechs then i must ask if you been playing at all!? Because my complaint is rather how fast they are giving out legendary mechs and weapons and not the other way round.. As soon as i figured out that saving a-coins and credits is a way to go life changed for me. Took me a while i admit.. But Volti cant do anything against Salvor.. But common, uncommon, rare have no chances vs Volti, i agree 100 %, but only until they make a sniper weapon that hits through all walls you cant win that matchup.. just come back in a year, obstacles will not be a thing anymore, there will be 25 weapons shooting through walls and give EMP effects with 30m radius blasts
