What would be the best MK 2 Enforcer Build

It’s all about opinions and there are no ‘wrong’ builds.

I think mk2 only has two weapon slots, so I’d go for standard cannon and sniper. Both have good range and shot speed so easy for newer players to pick up. Standard cannon also has short cooldown so you’re not waiting to shoot. At higher levels the standard cannon will become redundant as you’ll focus more on higher burst damage, but should be great on a mk2. Sniper will allow you to shoot those higher mark ships that you’ll soon be facing from a safe distance. Sniper is a good choice at all levels, but later in the game you may find a blast cannon suits your play style. OB and TB as previous respondent mentioned are good choices (I still use them on my mk6 enforcer).
