100% working class ?

Which classes are working on 100%?
I love playing with MG but there is a weapon skill bug + not properly working Flame strike + Power slash bugs that ruin my AFKs.

Which classes are working well with minimal issues that can't ruin my gameplay ?
Please give me some suggestions.

 

It's when I use MU Helper. Ok my char is moving because picking some items from the ground. So he move from point A to point B. After that he return to point A (his original position) because thats my Helper settings. It's kind of visual bug but not exactly.
All the monsters are around this point A where my character is supposed to be but I see my character at point B where he use Power Slash and Fire slash killing the flies in the air . He can't hit any monster because he is not at point A. But he thinks he is so he continue to attack and attack. Until my pots are out. My char is basicly stucked.

Thats the reason why I put Fire Slash on delay - because Fire Slash hit close range and most of the times manage to kill the mobs and to unstuck my character. But this don't work every time.

I'm not sure if I explained it fair enough.

About Power slash , Fire slash better than Flame strike. Some MG players prefer using Flame strike and they think that with Flame strike monsters are dying faster. So I wanted to try that. Also is it True that Flame strike hit through SD ?

 

OK I'll try recording a video.

So MG can't use its strongest magic ? And elf , bk , sm ... can ?
