As all Dawn of War games have done, Imperial Guard, and the other races/factions, will undoubtedly be released as DLC. In these modern times, with modern technology, I think that what I'm about to say will at least be feasible, also this is my personal opinion for what would be great for DoW3 involving Imperial Guard, If you have any ideas, please comment.
1. There are many kinds of Guardsmen, from fatalistic
DoK, to bland and generic Cadians. So wouldn't it be great if you could play as them all? In DoW2, they released a Tau Commander and Necron Lord for Last Stand, so what if (they could do this for most if not all factions) released customizable army conversions, say like you like the Tallarn or Valhallans, spend probably $10 max for a conversion that you and everyone could admire.
2. No more Storm Troopers, I was never a fan of the Storm Troopers in DoW2, I much preferred the Kasrkins in the first game, and with the above statement, you could have Grenadiers or Devils instead, I don't know what the other guys have so they could probably use Storm Troopers.
3. I'm sure many of you have heard of or played Ultimate Apocalypse, any of you who played
IG might remember a certain little thing involving a Zerg Rush of Conscripts. They should have Conscript Squads that are weak but plentiful, more cannon fodder Guardsmen. Also the level of customization and variation in
DoW:
UA was amazing, and something like that should definitely be in the new game.
4. Heroes, since the gameplay trailers and footage, they have announced Hero Characters, of course this is nothing new as Hero units have been around since the first title, but
IG heroes would be a little difficult, the last game featured a Lord General, a Commissar and an Inquisitor, I think for this game, they are going to, regardless of this forum post, have a Lord General, Storm Trooper Squad, and the third one will most likely be a Lord Commissar, a Tank Commander of the mighty Baneblade or a Primaris Psyker. It's just a theory, a- I'll stop now.
5. Bases, since they are bringing back Base building and management, then they should bring back Defensive structures, the barricades in DoW2 were all right, if not a little flimsy as wet toilet paper, but I mean Bunkers, Walls, Turrets and more, after all, there Job Description I do believe is; 1.) Die, 2.) Die Standing, 3.) Die for the Emperor or Die trying, 4.) Hold the Line Dammit!
As a little side note of what would be great is in DoW2's Last Stand and multiplayer, you could customize your Hero to a certain extent, but what if they featured a far greater customization, as in have a little tab under Multiplayer or Army Painter that allows you to customize your Heroes, like what armor and weapons they will have for the matches you'll play, armor being more aesthetic in a sort of sense. Maybe change the Baneblade to the Stormlord or Shadow Sword. What kind of Power armor your Chapter Master is wearing, or... what... Shiny Rocks... your Farseer bedazzles his/her skirt with?
Anyways, that was just my personal, totally fabulous and Magnanimous and humble opinion, if you have anything you'd want to contribute, change or talk grox manure about, please post a reply.
