Pure str Blader
Pros: -You are a tank , able to survive multible mobs on you without dieing.
-People will be afraid to pvp you as it is very difficult to kill a Full Str Blader
-The combos look very cool , Best looking skill ingame. IMO
Cons: - The lvling speed is ridicculously slow
- It is Diffuclt to kill Players , even harder now with the Mana Shield.
- it is sometimes hard to find a good blade with high crit.
- you will be ksed for fun..
Pure Int Sword
Pros: -the lvling speed is much faster than blader due to Nukes. ( lv 30 Skills )
-As a nuker you do alot of damage
- ppl cant ks (killsteal) you.
-still can get those cool looking combos:)
-effective in pvp.
Cons - Low Hp
- not as good of a tank as a blader
My Opinion
I would say that Pure Int Sword Shiled is better in Both Categories. Pvp And lvling. It lvls faster because it has nukes, and i believe it is better in pvp because of the new Skill caleld Mana Shield which absorbs physical damage for exchange of Mp. With this skill Pure ints have become alot stronger because they are able to tank more.
If you still wanna make a blader then Go for it

whatever floats your boat. If you do make one though then Atleast have a gt ( Gold Ticket ) because if you dont then you wil lvl very slowly.. Get a wolf aswell
Hope i helped.
Sincerely ,
