Tip: Multishot and damage type mods make a huge difference, gameplay wise.
I struggled, too, with Zariman, then I experimented with a galvanized multishot mod, and things became so much better.
A TwinBee sentinel and some Metal Gear weapons would be fun, especially from Revengeance. A pyramid head helmet would also be pretty fun, but also a bit goofy-looking.
What companies would you really like DE to make a partnership with?
For me, it would be Id Software, Bethesda and Capcom
I salivate just by imagining the stuff we could get out of such partnerships
