Too provide a better balance, playing experience and challenge for all people :
Add ECM to the matchmaking criteria.
Size class criteria;
Ecm criteria; (How many mech with ECM)
BONUS critera (for even more balance)
Don't put more than one premade group (3 or 4 people) on any team either.
Even if it add a few (up to 30 sec) seconds before finding a match, it will provide more balanced result.
Consider this :
As people discover that ECM is very important, more people tend use it for soloing; (a mech with ECM will score more all the time)
Premade of 4 always use one or two and sometime four ECM;
In my own premade of two to four people, i will always take an ECM able mech, if no one has taken one. With the addition of ECM criteria, we could try to all mechs without it !
So matchmaking create weird match like one group has two to six ECM ( like 3 Atlas+ 3 ravens) and the other team has none or only one. Or it create the opposite too many mechs with ECM in the match.
So if one side has it and the other not, it create imbalance and it's not fun. Too many ECM mechs are not fun either.
Adding ECM to the matchmaking criteria should improve the game !
See you in game !
