Most weapons in this game have their own unique utility regarding effectiveness in their respective map-depended territory. Exceptions to this are minor differences in terms of vartierty, i.e, shotguns and pistols on narrows or close combat C4 and rockets on maps with holes. Grenades are a special case because they pretty much combine mortars, pistols and rockets, all the while excelling at getting high kill streaks and points. They can be used as instant TNT (also on flat maps), killing stuff in the direction in front of you and even as quick mortars when facing a height disadvantage. Aside from that, they are too fast too dodge if you aren't using /mark and pre-evading any possible weak points. On top of that, they are pretty much the most used weapon for 'skilled' players at the moment. Why is this bad?
Considering:
(1) monetary efficiency
(2) use/kills ratio
(3) usability % on maps/versatility
(4) price
(5) skill required
Grenades rank highest. (Obviously, there are relations between (1) to (4) and (5) if we don't assume maximized skill). Using non-upgraded mortar as an example, it's apparent that it has little versatility and usability on maps and therefor ranks as a below average weapon as a whole (exceptions include Frontier, Prison and most maps with cannons). Grenades should be changed because they rank too high on 1-4. I'll cut this short here.
tl;dr: current grenades are OP and make the game one-sided, one fix could include nerfing their speed (credit to razinao), also removing diagonal upgrade could make them less versatile
