By claiming it is weaker, you appear to be ignoring the fact that the entire game system was rebalanced and that you now only get 1 Attack Action per IP, which means it changed for EVERYONE. Originally the Longarm user needed 1 RC, now they need 0, for example. Once you actually acknowledge that and move the debate to the Recoil topics, I'm willing to consider your intent to debate genuine. Until then, to my eyes you're just trying to push your point through while deliberately ignoring the game rebalances.
In SR4, you had to do 1 LB and 1 SB each IP to keep up in combat. In SR5, you need 1 LB. Furthermore, you now have 1 more RC available. So the Recoil changes, under the errata, did NOT make Gas Vents any more required for proper functioning in combat than in SR4, and mainly put less pressure on the wielder. Claiming otherwise is pure foolishness.
As such, in my opinion there is no need under the errata to have the two combined. If one ignores the errata and houserules it takes 1 Action Phase to reset recoil, then I consider it perfectly fine to have the two combine. No matter how much you ignore the game rebalance, that opinion won't change, and any recoil debate on it should not mess with this topic and be in the recoil topics, as I already said before.
