My biggest gripe with AOE 3 has always been the deck system, I feel like it's a massive knee cap for new or revisiting players, as they're against people that can infinitely spawn units for free during the middle age. There are cards that are outright better than others.
I can see that the development team put in a big amount of time in making the home cities et cetera, but I think that by either opening all options for the player in online play, or using the card tree as a sort of specialization (ei: do you want free soldiers/workers in your shipments? or do you want unit upgrades?), you can open doors for more efficient deck builds and more varieties of strategy.
Rewarding only players who play the game consistently and closing opportunities for players to explore until a player loses enough games is limiting and disencouraging. Whereas in the vanilla game, early game rushes through shipments is a common strategy, it seems to be the norm in WoL online.

Another suggestion, since I didn't want to make two threads; I notice that there is already a wikipedia page posted about the mod on a seperate .wikia.com domain, would the mods be in support of officially hosting a wiki page on this domain instead? Wikia is notoriously difficult to navigate due to clutter and a plethora of ads.
