if you dont enjoy PVP and thus dont play it, things are so much easier
you can go max determination, rest to proficiency, defensive stats go vitality & bloodlust, end of story
(ofc there are a few variations like brutality for PVE where mobs have large HP pools or supremacy being useful in some special builds but in general you are set with the above)
i am so annoyed by changing stats and builds everytime between pve and pvp i usually just stay in pvpbuild and accept subpar performance in PVE - its still more than good enough
stats are far from bland, let me go into detail a bit
proficiency is the simple stat - the more you have the more damage you do but its always the same
brutality is very interesting - the lower your targets HP are, the more dmg you do. this is very intneresting for PVP in order to finish off healers and also players with high caution (defensive stat that reduces damage a lot if HP are low)
when i play psi i love to go full brutality, first tickle the enemy and make low damage, it seems like my attacks wont do much, enemy feels safe, then keep up pressure and then burst and create a big surprise as the multiplier from brutality can hit really hard. experienced players know and can cope with that but its very satisfying when you battle non-veterans
determination has a special mechanic, you have to keep up your gauge to do proper damage, i think it has to be at 66% to be equal to proficiency but if your gauge goes higher, it will be more efficient than proficiency. in PVP you usually have to AOE to use it reasonable which is a significant trade-off as you will suffer from the low dmg in 1vs1
some time ago, the mechanic was to fill the gauge by RECEIVING damage, not causing it making it a great stat for tanks and an interesting option for PVP as it was basically a punishment for those attacking you. result was noone atacked those with high det but they also could not deal any relevant dmg so after this was widely known the fun was over
also, when AOE damage was 15m radius on average (now its the half) deter was AWESOME, i remember as warrior going to assault (normally played as 2h-tank in PVP), full deter, full bloodlust, into enemy groups, doing the warrior-spinning, healing with bloodlust... almost always #1 in damage with so much space to #2, great memories
ok, now we have covered the basic stats
lets go to the special stats
for some classes supremacy works better than others
for example for necromancer its a boost without issues, you just have to stay away from other players
for demonolog however, if only boosts your seal-attack means all statpoints put into supremacy willreduce damage from your torture which is one of your main attacks - but it will also make you gain the resource for seal faster... thinking about all that, balancing and so on is a tricky task and somehow enjoyable...
luck is also a factor, makes you hit a bit harder but since you have a counterstat in PVP for that its less relevant
maybe if you go PVE only full luck is a good idea? i have never tried it
i recommend you spend some time with the new stats and take time to read about how they function in detail
