At least thats what it feels like ontop of already ''miss'' and ''resist''

is it because the weapon skill takes into effect in wpvp?

Probably better equip and more skillpoints in crit things. For example many warriors only start to put points into cruelty in fury tree for 5% crit when having mortal strike. That means at 45 he will have 5% more crit. And level 60 will have farmed gear which has crit on it already. And his gear might be more tailored to his needs. Ive worn +spririt/strength rings because I couldtn find anyhing better for a long time. Therefore its normal they have higher critchance.

In PvP the weapon skill (before any +hit or +weapon skill from racials or gear) is always set to 5 x your level, regardless of any weapon skill you have.

As an example, a level 30 will have a weapon skill of 30 x 5 = 150 for PvP.

As for crit, I feel it crits more when higher level targets hit lower level ones, but I am not sure that that is actually the case.

No, not in the context that you are saying.

However.

Yes, in terms that a lower level player has less defense yielding a higher probability to be crit due to .04%Chance to avoid being crit per defense skill attenuated.

Well, +skill gives, among other things, +0,04% / point even after Weapon Skill > Defense skill, doesn't it? I'm not too sure, but if it's the case then yeah a higher level character should have more crit versus lower level than versus players of his own level.

A level 60 has 60 * 5 = 300 weapon skill for PvP purpose and a level 30 30 * 5 = 150 defense skill, which would result into 0,04% * 150 = 6% more crit.

Critrate in the spellbook is against a target of the same level.
