Currently system gives you a 10% bonus on both INT and STR per class rank you have and I think it should be moved to be 10% bonus of your MAIN stat, as in the one which you spent most of your points at because of these reasons:
This game kinda rewards you to have a main stat with it’s current system of getting bonus points the more you invest in a particular stat, but this justs gets coumpounding better when you also get bonus stats point for STR and INT, and makes them just better than the other stats overall.
About the builds themselves, all I know is full CON build are good on Cryo3/Chrono 3 or in PvP overall, while in the DEX vs STR debate: I heard that full STR does way more damage, but DEX wins in the solo departament beacuse of all that bonus evasion you get (I may be wrong on this).
But speaking about something I do have knowledge of (I’m a main SPR Priest player): priests got that kTos Blessing buff, which will make blessing scale with INT and SPR (0.2 and 0.6 respectively) which makes SPR 3x better than INT. Problem is, with this current system, this is still kinda biased to INT builds, when rank 10 reaches(Long time I know, maybe pointless to talk about it), every STR and INT build will have 100% bonus points, making this hipothetically scale 0.4 against 0.6(or 2:3 ratio), which almost makes INT scale better than SPR on blessing alone, while INT users also get much higher damage on every other skill they have.
In comparison: level cap of 280, builds with 300 invested points:
50 CON and 250 Int gets 534 int, which leads to 106 Blessing DMG (2590.2)
50 CON and 250 SPR gets 335 SPR, which leads to 201 Blessing DMG (3350.6)
So in the current game of 280 max level cap, the scaling itself is already at (1:2) instead of the supposed (1:3) which leads me to believe the current system is unfair, and developers aren’t taking this into account when buffing classes.
If this is done, maybe even the blessing SPR scaling could be toned down. I just think it’s better to solve this issue first, and then buff SPR/DEX classes accordingly, instead of buffing them with numbers that may seem like they’re fair, but in-game they’re much weaker than they’re supposed to be had you gone INT or STR.
TL;DR: I think your MAIN stat should get 10% bonus per rank up, current system benefits STR and INT builds too much, and I think they’re balancing the game without keeping that in mind when giving skills Hybrid scaling.
If you have better opnions and math claims on your CON or DEX build, please feel free to post them here. Also sorry, my main language is not english
