at level 34, 5ATT is more than 2% difference in damage. it's easy to see this... 5 is 2% of what?
x*.02 = 5
x = 5/.02
x = 250
is your ATT 250~ at level 34? if you're getting 150~ ATT from somewhere other than skill it is, but you're probably not getting that (possible with buffs).
why is this division thing relevant? damage is: base damage * pDIF, and pDIF is a number close to yourATT/mobDEF minus level correction. notice that when you have X/Y = Z, increasing X by a certain percent also increases Z by the same %. example:
10/5 = 2
increase 10 by 50%, 10*1.5 = 15
15/5 = 3
what's 2 increased by 50%? 2*1.5 = 3
in other words, without actually doing any math, you know that your base ATT is going to be relevant, at early levels, 5 ATT is going to be more than 2% DoT.
there's more though. suppose you did have 250 ATT at level 34. level correction makes ATT more potent. [it also makes mob DEF influence the exact amount of DoT you get from ATT, but we'll abstract away from that]
say you do have 250 ATT, and you fight something 7 levels above you with 200 DEF.
250/200-.35 = .9
255/200-.35 = .925
which is a 2.78% increase [more if mob DEF is higher, incidentally]. the point being that it's not .02 even if 5 ATT is 2% of your total ATT, unless you're fighting EM or below (so no level correction).
in summary, your friend either doesn't know what he's doing, or he was comparing with giant level 75 ATT levels, in which case you and he should be wearing dusk gloves or hachiman kote for 5hit and not worrying about red hands.
