I have adjusted to it and tbh the only time in D1 I r5eally consumed synths was with darkdrinker and gjallahorn and that was usually just dicking around on patrol. But I did used to make the synthesis a part of my end-game strategy....whether it was in Chellenge of Elders, or Nightfalls etc etc. It required mathematical precision to smash your way thru an event and still hit the boss with a full heavy ammo. I did miss them at first but I have adjusted. I havent got those weapons in D2, the sword I have generates its own ammo (so never really runs out) and my other main heavy is the Single clap sniper which holds a decent amount of ammo. I always seem to have ammo, if not theres always loads lying around A few precision headshot kills will generate some easily anyway!
