SET'S/WEAP'S that SUIT/BEST for every CLASS

Hi! Good day everyone!
Well, as one of the concerned citizen in this community, i would like to voice out one of my problem and maybe the same for new members/players or old players who played again. XD

We need help. Can somebody make a tutorial or list of sets/weapons that best for each class?
i.e.
if you are a chanter and chose to be full support, EA chain is best for him because maybe EA set has high Magic Resist and he can be full MR.
OR
EP chain set if he want to go full block because EP chain got high pdef of high block stat?
EA chain vs. EP plate, ETC...

especially today, i see a lot of shoutings about SEE/SEA/EOD/etc...
man those items r very confusing and is hard to differentiate its differences.
XD

if anybody from the staff r not busy, please help us out! thankies!
