Telesto is the best. Lorentz is great but I’ve never had good luck with it in PvP even with it being pretty strong. Merciless got hit hard with the changes to high impact fusions and should see a big boost next season with the buffs high impacts are getting. For PvE it just needs a buff to its reserve ammo, it’s got the lowest inventory size of any fusion on a gun designed to eat through ammo. Don’t know if it still decreases its damage when its charge rate increases in PvE, if so they need to get rid of that.
