That's the problem with meta builds. They are Usually built by the pro players, for the pro players. They're often hard to play at first and hella pricey. They also need good trigger discipline (in general), patience and a fair amount of practice, which could scare people off. (Examples would be the timberwolves with 3/4 SRM6 and MLs. if you went SPL instead, you'd get longer lasting dps. Or the tbolt with 3erppc that Was the meta even after the nerf, but i went with 2 ERPPC and a couple MLs and more heat sinks

)
The hunchie mastery bundle is pretty good tbh, and it Does teach great discipline. Except for the one with 2 SRM6's, I still don't really like it...
The tbolts take a bit of practice (and need to be elite'd at least), and tbh i was slightly disappointed by the hero. With all those nice highish hardpoints and 5% quirks? *sigh*
Anyway, apologies to the OP, I got distracted... The Wubbolt is amazing, and I also kinda like the 3LL tbolt, but the ERPPC one (imo) was too... cumbersome and difficult to play...
