UEF sucks in 1v1s and team games. Here's why:
1- Worst T1 tank. The Striker is slower, has lower DPS, and is more expensive than Mantis and Thaam. It loses to them 1v1 and in groups.
2- T1 bomber is good against structures but not against units. Easily worst bomber against Auroras or other mobile units.
3- Most unarmed structures - mex, pgens, factories - have more health, but this advantage is offset by most expensive T2 artillery and T2 PD. If UEF is turtle faction, why have most expensive defenses? The T2 PD and T2 artillery are not bad, but they aren't any better to justify increased cost.
4- T2 land is not very good. Pillars and mongeese are spanked so hard by Rhinos it's ridiculous. UEF T2 land isnt as bad as Aeon's, but it's no advantage.
5- T2 air lacks a good snipe option. This is a huge weakness any way you slice it. Janus is only really good against T1 units and structures and is the worst bomber for killing T2 pgens, mex, and acus.
6- UEF T3 land and air are decent, but not advantageous enough to offset the disadvantages of T1 and T2 stages.
7- T1 navy is almost as bad as Aeon's. T2 Navy is worse than Aeon's with worst destroyer in all of FAF. (Although UEF's T3 navy is very good.)
Overall, UEF's main strengths at T1 and T2 are tough ACU with cheap nano upgrade and unusually tough base structures. I think UEF needs a few small buffs, and targeting these on the T2 PD and T2 artillery are the best places, I think, to give UEF a few extra avantages. Maybe the torp launchers, too, to help with navy (And because all torp launchers suck.)
