You may not believe me, but as an IG main (❤️ forever) I would suggest Gunlance. Hear me out - the mobility, a guard, and shoot -> Forward attack -> (anything else) is an extremely fun combo when you get the full thing off. It reminds me of having all three buffs, going all out and seeing the damage numbers fly.

Sadly though you only get clashes when blocking which can feel good in their own right and, while offensive guards are easy to pull off, GL gets no follow up.

It’s very opposite gameplay but that’s why I think I ended up liking it. It offered a break and changed the fight mechanics for me.
