Hello! I am new to posting here, although I have been a ghost looking at different threads for the past few weeks. I am not sure where else to ask this, but here goes. I have played fighting games before, and I am finally making the commitment to take my game to the next level and attempt to be a more competitive player. Although I have not had the same attachment as most people here to MK (because I grew up on SF) the Injustice series really sold me on NRS, and I have come to love the fun and characters in MK and I look back wishing I played when MKX was active. That all being said I am really intent on learning Jax since I loooove grappler characters, but I am afraid that Hunker Down might gimp my fundamentals and teach me non-transferable skills (due to lack of combos and being grab heavy) to other characters should I want to do that. Are there tips, advice, etc you all can give me? Should I play Grinnin' instead? Again, I apologize if this is not the thread to ask. Thanks in advance!
Play Baraka.
Edit -- that probably sounds dismissive, so to explain:
Baraka will teach you better NRS fundamentals than Jax will.
Baraka is a little less reliant on KBs so he forces you to learn good habits -- footsies, knowing your turn, reading, etc. -- instead of falling back on crazy sequences of damage as a crutch, outside his one 50% in Marauder.
Baraka has a command grab with way more tick options (and ability to do it from range) if you play his Bone Picker variation, so you get a better feel for when to use them, how to mind-game with them, and they don't have a 4-7 button input or cost him meter to be worth a shit.
Baraka has more reliable and more effective zoning with Blade Spark than anything Jax has in his entire kit (since missiles cost heat resource) so you get a better sense for how that should work, too.
Baraka has real combos, unlike Jax, so you're forced to learn block/hit confirms in a way you really aren't required to with Jax -- he doesn't have a good "safe" cancel on block confirm outside of BF2 amp -- how staggering is intended to work, etc. Baraka has a non-corner restand on strings that would normally end in knockdown just by canceling into Blade Spark. Baraka has the two simplest pressure strings in the game. Etc., etc.
Baraka is who you want if your aim is to understand NRS fundamentals. It's almost like he was designed for it.
