Wizards, can also get Vit, especially for PVP. And there are also some unique Agi Wizard builds (high agi = can't be cast cancelled even without no cast cancel gear opening a lot more possibilities for armor). You can also get a little STR for weight capacity, although hardly anyone does this. In theory however you can even go for a full physical attacker Wizard as the class can equip some quite interesting weapons like the counter dagger with gives you 90% crit chance. And LUK you at least can get it to 10 with your class bonus as it's cheap and gives you a 1% lucky dodge chance.
Of course if you go for real LUK builds you usually don't use skills, but instead use normal attacks. Except that there are some skills that actually CAN crit (not for Wizards though).
Priest can use pretty much all of the stats even better than Wizard. Physical attacker Priests are quite viable, especially if you have a Battle Blacksmith to party up with. Priests need LUK for Turn Undead success rate. AGI reduces cast delay on some skills and also protects you from being cast cancelled. Not to mention that depending on the skills you get, wtether you want to participate in PVP or not and whether you are a full support are an exorcist type the optimal distribution between INT/DEX/VIT will always be different.
