It depends on a lot of things.
difficulty changes over time.
you might find a huge mech or strategy is utterly worhtless once you hit a certain level.
you might realize thepat the refreshing leageue of level 10 to 6 work, ut your mech is t verry effective beyond that.
maybe you should just hpchange how you play.
when i learend that you could ypuse charger to force your team to win even if your team is weaker in cpc, i had fun.
i also had to learn when to sence that if you do certain things in a away and a spot you will find yourself in a situation where you are going to die no matter what choices you make, so you do things for a while and follow your protocols for the situation and map, and boom, people coming around the corner you shoot and hide behind something. Often times two or three will cover anything you would have tried if you stayed there or even moved into spcertain areas.
for a mech that overcharges, i would sugest watching players an bots until you can oredict when to walk in and overcharge them. Get in fron and block incoming damage, while not blocking their shots from them to your enemy. Let sheild units get in fron of you and behind you. do that enough and you will attract medics and perhaps people who want boosted shots.
