The nukem and kick charger are the only two heavies I used in bl3. As for grenades, I only ever used 2 or 3 different ones. Most were absolutely useless end game. And the ones that were ok end game need buffed. Scaling end game needs addressed. And I hope bl4 doesn't suffer from the same scaling issues found in bl3. I still play bl3 with over 1200 hours so far. Very much looking forward to bl4.
Better writing and storyline like BL2. Bad guys who aren't social media "influencers/content creators." Oh, also, DLC characters with the likes of Mr. Torgue and Moxxxi! Please!
