I think that in a team there should be a requirement to have atleast 1 engineer, 1 medic and 1 support merc. I’ve lost so many games due to the fact that I’m the only engineer and there is no medic to heal the team and me. This just leads to our team being massacred in every life. Having a bad merc lineup also results in ‘stomps’ a lot of the time.
In addition to this I personally think on the whole defending is far easier than attacking on the majority of maps. Most of the time the defenders lose is because their team chose a bad lineup of mercs.
Maybe tips on how to complete each objective would be good for some of the less educated players. For example throwing down an airstrike on the last objective of chapel can easily clear the area so that your team can push up and deliver.
