exploitation of mechanics created some of the deepest gameplay yet. Quakeworlds entire gameplay is now based off an unintentional movement glitch that caused movement to be much more dynamic. Stacking air units in Starcraft made some very deep and mindful tactics that would never be possible without them. Dolphin diving, prone-spam, squad switching, and C4 chucking made for some very exciting matches in BF2 and made the game overall better than after it was patched out. Strafe jumping in Quake 3 made movement much better and game flow alot better. People exploiting glitches is a fundamental example of pushing a game to its limit. And as long as dynamic combat comes from it, a solid counter is found, either through skill or style, then it is acceptable.
PUSH THE GAME BEYOND THE INTENDED LIMITS
The best games of all time were "made" or fleshed out because of this
Starcraft, quakeworld, quake 3, and Street fighter are built on glitches and stay strong to this day.
said in a post i made earlier, but seriously, there are probably reliable counters to it. There were reliable counter to C4 chucking in BF2

If that can be countered, and it was, still a part of the game, Then this jav shit can be countered with ease. This was early on in BF2 when people were still figuring out the game, eventually it was countered with a style shift in competitive players adopting the assualt class, and a heavier emphasis on staying apart from one another during pushes.
