I am really struggling here man
I managed to reach Champion with this hangar, but damn is the champion lobby stupid. It's either that flying pest with the brrrrrrrrrr weapons, or the flame throwing robot going zoomies on the map. Also, how stupid is the Rex, a MK2 Rex with Mk2 acid shotguns just deletes my titan? How? How am I not doing damage to him? Rex users just keep pressing the ability button hoping it does something while spamming Advance Repair Unit.
Anyway, my question is, how do I compete without spending? The weapons I have on my hangar are the only ones that are upgraded enough, should I keep investing in these weapons or do I change something?
