The best would be Fire/Ice however this is moreover good for PvP .. you suck pretty much at grinding due to your slow speed.
+Max. Defence with Ice Buffs and Fire Buffs
-No Speed
If you skill 100Heuk 100Fire around 90~Light and 30~ Ice (you can go a bit less ice or more ice for low Lvl SnowShield) you have a nice Speed, and still strong enough to kill your enemies and on FW/GW you dont need to wait for a bard or rely on drug speeds to be fast enough ..
+Average good build
+Parry Ratio Increase
-Less Defence
The third build would be a force Glavier, but its kinda hard to find opponents which arent already buffed with HolySpell .. well, this is only made for PvP but again you have no speed ..
+The chin Warlock kinda
-No Speed and you have less Defence too
