ctf_dirtbowl is shitty for 4v4s. Every team requires a runner to grab the intel, and a constructor to stop runners from grabbing your intel (aka camping). Any attempt to try and be cute with your team composition or positioning gets punished severely with runner backcaps that are almost impossible to stop once it is outside your base (keep in mind that while it is easy to plop down an autogun to defend a choke from the enemy resetting the intel, it in turn over commits your defense to an entirely separate path). This leaves 2 spots for other classes, and healer is non-negotiable, so really 1 class. It could be either overweight or rocketman, and overweight+healer beats rocketman+healer every time.
The optimal team is:
and any attempt at another setup is going to suck. Replace
, and you're going to get meatshielded, run out of ammo, and get out-dps'd by overweight+runner. Replace
with any other support, and you're going to get back capped or it will force you into bad defensive positions. For example, if you replace constructor with rocketman, you can easily find your push out of position to defend a backcap, which therefore relegates your runner to full-time defense. In the meantime, their runner can always choose to fallback from any offensive position to flank your push. If you replace
with anything, and you're going to be hard-pressed to get the intel out on offense, and you're going to get fucked if you're forced to chase opposing runners.
The only more effective team setup is one that is adaptive, switching out the
depending on each team's overall position. But from as far as I can tell, no team is experienced enough to pull off something this ballsy (seeing as though they're all draft teams).
This should be enough for anyone to veto ctf_dirtbowl from 4v4 competitive play. Overall, the map isn't very fun to play with small teams, because it's pretty much ctf_conflict size, except with way more twists and turns and forks in the middle of the map, which makes backcapping more prominent and 4 on 4 engagements less so.
