Yeah, I have done a few things on the wiki, well, what I can do with my limited knowledge of the expansions. I contribute on several other wikis and am an admin on the StarCraft Wiki, so that is nothing new to me. Someone definitely needs to give the Diplomacy features some love on the wiki, I only know so much. I added the envoy cruisers to the wiki with what little I could find on them. So the envoy cruisers are named the Neruda Envoy Cruiser (TEC), the Herald Envoy (Advent), and the Voruntak Envoy (Vasari), respectively? If so that would make them the only ship class that actually uses the function name in the class name for all factions.
I think I will just buy both Entrenchment and Diplomacy sometime next week, so I can devote enough time to get a feel for the changes. It is not like I have to play Diplomacy right away. I know Diplomacy builds on Entrenchment, I assume that must be how micro-expansions work. I haven't fought the harder AIs in vanilla yet, but I think I can handle them, it is not like this is my first rodeo for strategy games. My college finals will be done by then, so I can burn some time until classes start up again.
