Is 3 plate equipments a must if i want to play end game contents? since i have Wind runner and its pretty good considering its synergy with semediveve, i want to keep equipping it all the time and non plate gloves for magic amp, but i heard 3 plate equips and its attribute is a must.
is it basically true? wind runner isnt good with bokor doctor??
I don’t think it is a must, but if you want more phys def it would be in certain way, aside from gloves, i don’t see any other type gear that would help much in that sense.
That way you have a small boost in def while keeping your WR.
Gear wise, anything that increases your offence or defence. Anything at all really, its not important since you have no need for sta or sp pool. Just gear towards what you might think may be better. Generally more hp is always welcome and halfing npc archer damage is also benefitial so most people go plate. Do what you want. You’ll probably want a cloth set of gloves though.
As for weapons. Pick up a krausas mace asap. It will do you until a +4 superior corona rod at level 220. The dps it adds is just that good even though the matt on the mace is measily. In TBL you will also wanna use the krausas since stats are scaled up making it infinitely better than anything else you can get your hands on.
Jewelery is basically the same as armor. Sure you can get archmage bangles and max peta and etc but honestly, anything that benefits you is best.
You can play plate or leather with 3 parts but cloth gloves are a must have.
Rokas Robe (Cloth) is also pretty handy. Im 280 and still wearing it in some contents. It gives alot mdef as a standalone gear piece.
Why not both? 
I have both Wind Runner and dodge boots on my quick slot. I switch depending on the situation.
