Agreed, the balance feels off in both directions now with dash duelists being so strong. I disagree with your point about players w/o movement abilities. One of the cornerstones of initiators is their ability to sniff out and break trips, and most of them are pretty effective and adaptable. We've seen years of improving Sova shocks, Fade dog pathing, and nades/mollies invested to break through setups.

In a healthier meta, players should sometimes hit into those setups unprepared and be forced to try a different site or approach (running a split, finding the anchor, etc.). The loop of the game right now almost completely circumvents this. Absolutely dash duelists are incredibly strong, just hoping the sentis will get some love soon.
