Completely subjective ofc but I think the teamgame experience in CoH3 still isn't fun, that's the big problem, and teamgames are about >90% of the CoH2 online playerbase.
Teamgame players want big tanks & explosions, not this light & medium tank spam
CoH3 is always Marder blob, Wirbelwind spam, P4 or P3 spam, Sherman & Hellcat spam, Crusader spam.... you name it. But apparently Relic's faction designers think that this is what teamgame players want, especially in 4v4
4v4 is bit weak because the fun maps are not many but we still have tiger and blackprince for late late heavy. some complaints of coh2 is because of heavy tanks stall, best of coh3 is no more >60 range AT just canceling out tanks.
there are also more big explosions in coh3 than coh2, because in part muni are plentiful now.
in terms of med tank spam, i hate 2v2 stuarts and crusaders, is lame because of how fast and impactful.
I think you can give 3v3 coh3 more a try.
What has actually changed that people are saying Coh3 is good now for team games? They finally fixed up the menu and added replays. It looks like a real game finally.
Team players like Dirty Finisher and Duffman feel like Coh3 is lacking too many mechanics. These are upper echelon players so their tastes may be different than 90% of the player base.
Aerafield is a top player and his complaint (see above) is the game feels like it peters out mid game. Its like playing Coh2 only to 15 minutes then stopping.
I state that Coh3 does not provide the necessary feedback to players, mechanics and sound.
LACK OF MECHANICS
Coh3 allows you to just blob. This is not engaging. This does not create exciting dynamic interplay. It does not "feel" as good to a player to A-Move a blob into another blob. The "good" play feedback comes from moving units tactically. Moving a squad or two here or there and moving another around to flank. This is the payoff our bodies enjoy. Blobbing does nothing for this. But most of the player base are not great players, so blobbing may be fine for them.
SOUND
The Coh3 sounds are lacking. A large portion of the player experience comes from the sounds. Each sound in Coh2 gives the player information. What unit caused the sound, was it successful, should I be worried, how close is it to my units, etc etc etc. Coh3 sounds seem to lack in this arena. Once again game feedback is the critical piece in a game.
MAPS
There are not enough maps. Some are pure cancer and you cant veto them. White Ball is the most played Coh2 map (ever?) and some people hate it. Some love it but will hate it after playing it 3 times in a row. Only having a couple 4v4 maps = dead game mode. If I had to play Lorch Assault every game I would uninstall Coh2 immediately.
GBPirate is trying to help out the community by having a mapping competition. Lets hope there are some great maps from that. And Relic (Mono) is hopefully still making maps so eventually the Coh3 map pool will be in good shape in a few months.
The interface and mini map are finally useful in coh3, yes that is a big part why it is pretty good now.
I dont think a blobbing is worse than coh2.
