I can understand taking out the pure point forward build, because that archetype at 6'10" is extremely cheesy and unbalanced in the current version of 2K18 that we've been playing. But I haven't come across any other build this year that felt like it was too cheesy to be available in this combine. Maybe you could add 7'3" pure stretch bigs to that list because of their ability to consistently hit deep threes over good shot contests and defend/rebound at a level well above their ratings due to their huge wingspan, but that's about it as far as "banable" archetypes go IMO.
I just don't see why so many archetypes are being excluded from the character select screen. DOTA and League of Legends both have over 100 selectable heroes, so why can't 2K18 be similarly diverse? There are no pure builds listed except for the SG/SF pure sharp and the center rim protector. The only perimeter defender build that is able to have its defensive stopper badge affect point guards is the one with the worst defensive ratings (sharpshooting defender). So if you want to play on a perimeter defender build that actually has good defensive ratings, you are stuck lining up at the SF position as a slashing defender, with a defensive stopper badge that won't be able to affect PGs or Cs. I would have loved to take my pure lockdown defender into this mode and go against some of the best offensive PGs and SGs that 2K18 has to offer, but that's not possible with the current roster of characters that 2K has come up with.
I have made seven different MyPlayers so far in 2K18, and the only one of those archetype combinations that is available to use in this combine is the playmaking slasher (my least favorite character of the ones I've created, of course).
I'm sure I'm not the only person whose preferred archetype mixes aren't available for this event. All year long 2K has been telling people to "perfect their craft" and "hone their skills." But how can you tell people that for 4 months, and then not let them compete on the big stage with a skillset that's at least similar to the one they've been practicing with all along? I am fine playing with slightly lowered ratings and slightly reduced badge levels, but being asked to completely switch archetypes is taking things a step too far IMO.
Imagine if you were a fighting game player and you spent 4 months mastering Balrog's moveset, but when it came time to qualify for a major tournament, Capcom suddenly decided to remove Balrog from the available character pool. Or what if you were a Counter-Strike player whose go-to weapons were the Desert Eagle and the AK-47, but right before a big tournament, VALVE decided to take those two weapons out of the gun store. That's basically the equivalent to what 2K has done by drastically reducing the list of available archetype combinations from 189 to 22. With one blog post, 2K has rendered 89% of this game's archetypes obsolete; and if you haven't been playing on one of the chosen 11% builds, then you're already at a competitive disadvantage before the combine even begins, because in 2K -- as in most videogames -- experience is the best teacher. Playing dozens of games on the same character is how you learn what works and what doesn't work in an online competitive environment. And it's only once you've internalized that knowledge that you can begin to play that character at its maximum efficiency, making only the moves and taking only the shots that you know -- from past experience -- have a high chance of succeeding.
