Theres alot of stuff not intended in FGs and most time it ends up making the game more interesting
Like MVC3?Runjabs in UMK3?T4 Jin?T5 Steve infinite?SFIV unblockables? I could go on forever.
Yes , there is lots of unwanted stuff in FGs and it can add depth but that depends on how you look at it , you could say "hey if you're mashing and not timing it you deserve to get meter drained" and another guy can say "i took a guess or reacted 1 frame later and nothing happened but my meter is gone this is dumb".
Honestly , can you blame the 2nd opinion about the meter drain?
People who get the meter drain aren't always mashing armor , maybe they're trying actually time it.
Thing is you can't know if the other guy was mashing armor or timing it when you're in game.
Obviously you can get better at timing armor by playing the game and react faster but that 1 frame of meter drain glitch will always be there no matter how hard you practice , 4 frame gaps are actually 3 frames with 1 frame of meter drain.
Knowledgable FGs players generally don't like randomness ( and while meter drain is not random the blockstun is definately "weird" in MK ) that's why laggy setups are the devil , when you get eliminated from a tournament ( or simply lose some casuals ) you don't want to be in doubt ( "Wow i did this but it didn't come out!" kind of thing ) about what you lost for , that's why an experienced FG player wouldn't like something like Meter Drain.
If anyone suffered a meter drain they at least want an indication they released the block button and that inputted the armor move correctly but it got stuffed in that 1 frame of startup instead of just being stuck in block and get meter drained. ( this may be hard to understand but trust me it's a huge factor for some players )
Cyrax resets weren't intended and yeah they make the game more interesting...for some Cyrax players , the poor Baraka player that gets 90% damage "GTFO the tournament" combo probably won't be happy about it and the only thing that can make it interesting is learning Cyrax itself , mind i totally understand the "play to win" mentality and i don't blame players for moving up the tierlist.
Input Bug is clearly unintended and while "yeah i can just time my inputs better" someone is going to fuck up and get a standing 3/4 and can use it as an excuse since it's in MK and you can't tell if they only pressed standing 4 out of panic or legit d+4 input bug. If input bug wasn't in it that someone wouldn't have the chance to scream INPUT BUG and you could say "hey you simply fucked up".
TLDR Yes unwanted stuff can make games more interesting depending what opinion said people have about the specific stuff , but unwanted game engine mechanics that are hard to control by the player don't make the game more interesting.

And by the way good stuff on your Kenshi , many hate Kenshi but i like watching it and few people recognize that playing good defence is actually harder than rushing down even with dat armor , keep up the good work.
