since it doesn't have the polish that Coh2 came out with
Mate, have you been there at release?

This is simply not true - CoH2 at release was horrible. Despite only having 2 factions, full of massive imbalances, lots of bugs, very boring meta.
As the core gameplay of CoH3 (4 factions, great faction design, lots of unit diversity, battlegroup system, shorter games, etc.) is excellent - I am not too worried. Relic seems slow but on it.
I believe DOW3´s fate was mainly a result of the very bad gameplay design, with overpowered hero units which made every other squad obsolete and completely chaotic battles with no real tactical element to control.
While I understand the frustrations of the community, I also truely enjoy the core game in CoH3. Relics development plan sounds reasonable. We all said it will take 6 months at least. I´m all up for giving them this time.
