Ill take free dlc over optional microtransactions any day of the week for the sole reason that it doesnt fragment the already small community.
I... uh... am not sure what you are saying here. Of course something free is always preferable to something that is not, so your statement seems kind of obvious? I'm not sure what you mean by microtransactions fragmenting a community though. Let me explain:
From my view (just my opinion), DLC and microtransactions can be done in ways that are subjectively and objectively better. The key of those being objectively better is obviously for a lot of people to buy them, having a clear monetary figure on the bottom line. Subjectively, it's a bit more tricky: Some people prefer microtransactions based solely on cosmetic/aesthetic purchases. Some prefer "short-cut" microtransactions because they don't have time to grind. Some legitimately prefer RNG packs because it's like a gambling fix for them.
However, a game that relies on one of those above listed models won't necessarily fragment a community as long as it is completely viable for a player to enjoy the game freely without the microtransactions. It is when games start getting into, say, Perfect World's shady practices (read: Pay2Win) that the community starts being separated by their real-life socioeconomic status. DAIMP most certainly does not do that.
The other way I can see a community become fragmented is if the game offers a paid DLC for MP that is required to stay with the rest of the group. Call of Duty is quite infamous for their map packs that are required to be downloaded by every player if they want to play on those maps. Conversely, Payday 2 only requires "map" (or mission-type) DLC if you want to host the lobby. If the host has the DLC, he can invite any player to come and experience it, regardless if that player has the DLC or not.
I know that was a long drawn out explanation, but I was just not sure what you meant by a community being fragmented, as I really don't see DAIMP doing that. All MP DLC (that could fragment the community) will be free, and the microtransaction model used in this game is about as anti-Pay2Win as you can get.
My complaint was that I personally do not like RNG or microtransactions based off RNG. The games that really make me rage about this are the ones that see mobs drop "lockboxes" that you have to pay real money to buy a "key" for it. If a game has RNG microtransactions, game developers also always cater the game around having it. They have to make it just barely boring enough where players won't quit, but many of them will resort to paying real money to skip some grinding. Otherwise why even bother?
I personally like aesthetics/cosmetic items, as long as I know with certainty what I am getting before I buy. I'd drop $0.99 in a heartbeat for a chainmail bikini for my Legionnaire, but that chest hair better be super-high res.
