these are the free mmorpg ive played:

-rose online
-kal online
-9Dragons
-knight online"this game is crap"
-Bots"not sure if this is an mmorpg but you can level up and upgrade and its crap"

ive playe allot of free mmorpgs i forgot them all

games that i havent played:
-2Moons

after playing allot of mmorpg's, what i still dont know is what dexterity is for,
according to cambridge dictionary dexterity means:
"the ability to perform a difficult action quickly and skilfully with the hands, or the ability to think quickly and effectively"

i understand it a little but isnt it the same like strength where you hit your apponent effectively?

you can google the games i mentioned if you want to play them,

No thanks, they tend to suck all the fun out of games in a neverending grind for XP.

Strenght would determine the amount of damage, dexterity the precision and execution of the hit, for an example.

EDIT:

i thought strength was HealthPower"HP",

so is dexterity attack?

HP is HitPoints
Usually Strenght affects the damage you do.
Dexterity affects how high chance you have to even make the hit.
Constitution usually determines how many HP:s you start with and how much you get per. exp. level.

I'm not a fan of these games, never been, but somehow I know this nerdy fact.

simple enough.
As said dexterity is your attack ratio. I would remember diablo 2 had something else but i dont remember what it was.
