Typically in most games, Support types goes Stamina - Defense - Evade
But this also depends on how the game's stat is set up
Most times people go Stamina because more HP = last longer and doesn't get one-shoted
Defense is the same, but some games have Stamina also apply to "action points" or "run meters". So people tend to just go for Stamina over Defense.
There are some support that goes for Evade, however all games have a "CAP" unlike Stamina. This means even with a max Evade, you don't really get 100 Evade, at most it's 75% Evade, so you still have 25% chance to be hit.
(Which is why some comments says Evade is stupid for MC, because they played games)

But this manga's stat system apparently has no "CAP" and also have "LIMIT BREAK" (some games also call it "Awaken" as to increase the CAP to the next stage)
What the MC got was a no CAP and he's already Limited Breaked to the next stage.
With how the manga's stat system is set up, all the MC have to do is put all points he gets from leveling into Attack, Magic and Accuracy. If I was MC, I'll just dump it into Magic and Accuracy judging by at the end of chapter 1 he said he has a huge mana pool. (so no need for attack/ physical skills - which is another manga's plot's "Close Combat Mage" lol)
