I don’t know. Maybe my problem is I’m too competitive. The play/pay to win elements are pretty strong sometimes and you need to try and counter them yourself or get farmed. You can get by with just bolt actions when the lobbies aren’t too sweaty. But run across a player with nothing but 20+ automatic weapon units and you will have a bad time unless your squads have a few automatics as well. Same goes for vehicles and vehicle counters you can bring into matches.
Too make matters worse. Resources spent at low and mi campaign levels are basically wasted. You can’t (reliably) recycle Tier 1 troops. They are just objectively inferior to Tier 2 and always will be. Small med/grenade/ammo bags are eventually obsolete once you unlock large bags. I don’t think backpack items are recyclable either, like T1 troopers.
