Additional data on stat testing, STR, ATTK, Base Damage

[Majidah]

Base dmg > Str > Attack power
Point for point STR is better then attack power, I think the rough ratio is around 2str = 1 base dmg and 3 attack power is 1 base dmg on equal lvl mobs, the ratio for attack power goes down making it less effective the higher the mob.

I have yet to find if using a few select ACC+ equips helps enough to be worth it on stronghold areas.

Also seems that STR+ is further modified when looking at WS's dmg numbers making it even more valuable then attack power.

If what you're saying is right; seeing we usually exp against mobs higher than our level, and how all bosses are higher than our level... wouldn't that mean atk power is then pretty useless?
And is there a soft cap on str?
