What's the faction(s) you guys have the MOST difficulty fighting against?, Just wondering about how you guys find difficulty on said faction(s) Options

So, I've been playing for a long and good while from now (around when ECA was first released on 1.8) and, with the gameplay of other peeps in Youtube, I wondered myself on the most difficult factions most ROTR players face off against. So, speak up down in this topic, and share how you guys deal with them.

For me, being a ECA main, it's Russia. Now, I could go on a very long rant about how they made this faction (least on the current beta test) TOO OVERLOADED that it's not even fun playing against a hard or medium AI on a map with big/no chokepoints, but maybe it's just the AI or (I can admit this) me still in on the novice-apprentice levels on RTS principles and strategies. Plus, personally, there are more important stuff to do other than rant about that godsforsaken faction. Other factions, I can do well against (US? Just build tons of AA, guard it with a few anti-ground defenses, some sensor arrays and a few Grand Mortars can do the trick. China? Tons of Guard Towers, Gun Turrets, and mortars, with the support of Wotans and ECAn aircraft. GLA? I eat that for breakfast due to their lack of armor) but Russia is the faction I'm finding myself saying "I can't do anything against this" when they go full unrelenting mode, even with the late game prototypes (Venom being my personal and absolute favorite). How I deal with them? Wait and hold until late game, have Frank Jaeger sneak into their base and nab some free cash while holding out, then get the Protocols, build me army, have Jaeger disable their power, combine the devastating power of two Solar Bursts, a Grand Slam bomb and a Smart/Neutron bomb then start the assault on their base. If something compromises said plan mid-way, retreat the most important units back, rebuild/improve army, and rinse and repeat. Works like a charm on choke maps.

Feel free to also rant about the said faction below, but keep it as minimum as you can.
