I can't talk about
1v1, but from what I have seen this mode seems to be kinda balanced now. The better player usually wins, no more "cheese > skill" matches.
In
2v2 I must say that -unfortunately- there is still a lot of cancer & abuse, almost more than pre-patch. IL2, Typhoon and P47 skillplanes got buffed and reached a cancerous level (as cancerous as Ju87).
You see them in almost every single match now.
Playing
OKW instead of Ostheer became questionable unless you spam Valiant Assault from the revamped Luftwaffe Ground Forces doc, cuz that ability is OP af now : 70 munitions,
45 sec duration (sprint + increased accuracy for every inf unit),
15 sec cooldown. Only JP4, Stuka, IR HT, some commanders and the buffed flak HT make this faction stand out now IMO. cheap vet 5 volks dont wipe anything on sight anymore while being almost impossible to kill. Panthers cost too much popcap
Ostheer is very solid now.
USF has a very strong late game now, that is because Jacksons are very powerful now and scotts are amazing like always. New P47 skillplanes add to that as well. Removing smoke grenades from riflemen was a necessary change, however it made playing USF vs early HMGs a little bit frustrating, and they still have the weakness that their mid game AT is weak (often it's pure luck if the USF AT gun will penetrate a P4 for example).
Brits became a little bit strange now. They still have the best mainline inf with 5-men bren IS, and fireflies are still amazing as well. Some of their former crutches got fixed(afk mortar pits being too effective and too hard to kill; password protection trenches to name two) They still have their big weaknesses --> no mobile and effective early indirect fire, no snares apart from 1 commander. However, in team games it is easier to play around that. British base howitzer is pretty good now.
The revamped Royal Engineers doc is pretty meh, but Royal Commandos doc has some very useful abilities now. --> smoke raid + mortar cover. New Air supremacy isn't as ridiculous as before, but still does its job.
Soviets are a little bit like an advanced Ostheer now. Pre-patch, penal spam and potentially some snipers was like the only viable option. Now everything is viable. Conscripts fit perfectly to maxim or sniper strats. Guards and 120mm mortars are a bit OP (since forever). Katyusha is still the best rocket arty in the game.
3v3/4v4 hasn't changed much. JT and Elefant are not so dominant anymore, they used to destroy every allies medium tank without any effort. Now they actually need support for this. JT became pretty meaningless because Elefant is better now (cheaper and more mobile). Still a lot of spammerino: team weapons (especially HMGs and mortars), indirect fire, and 2 click wonders (commander abilities).
TL;DR Apart from playing axis in 2v2, the patch improved the meta
However, thanks to this "Relic Scope", there are still some cheesy strats left.
