Don't forget to take back your 1H+shield after you used your bonus action. +2AC during your ennemie's turns is not that bad....

..... and send that greatsword to the next companion so he/she can use it at her/his turn. Like a round-robin kind of thing.
I'm a bit worried this kind of stuff makes it to a public release, and survives many patches for months and months. There's so much of it it makes you wonder if this is a Larian design principle more than an oversight. Maybe they like players being able to break the game for "player agency" or whatnot?
- cheating the game by switching items freely as described above (including switching armor freely for whatever magical properties you might need atm)
- Wizards learning Cleric spells and every class being able to use spell scrolls (breaks class balance and identity but probably "fun" for Wizards to cast heals and for Fighters to use spell scrolls?)
- trivializing combat encounters with high ground, stealth, barrels, shoving... so many options to cheese the fights
- the memes: eating pigs' heads for massive heals during combat, or building instant archery towers from crates in your inventory to get advantage, free "backstab" advantages
It doesn't feel like an accomplishment when using any of these exploits. It's all just a big meme, really.
