Nearly everything you listed there isnt even implemented properly.
Theres plenty of things I like about this game, if there wasnt I wouldnt still be playing. However I also know that if things DONT change then I wont be around for too much longer.
"elemental wheel" - Yeah I have tried this many times over, and it goes with the stats being broken (something yoshi has admitted to!). Being a conjurer I have tried different elements, boosting lightning affinity and carrying a walnut wand of storms while casting thunder II hardly does any extra damage against water types than casting earth or fire even without all those boosts
"Incapacitation"- Normally done just for better chance at loot (buffalo horns) but at times it can be useful in battle (knocking down buffalo with flashfreeze). This is actually one aspect I love but it doesnt have too many uses yet, and the fact that conjurer doesnt get any part damage without taking from other classes is annoying.
"Monster Weapon type weakness"- Dont play any melee classes but I havent really seen this make any sort of difference in combat, nor have any of my friends noticed it.
"Monster directional attacks received weakness" - isnt this a norm for pretty much any mmo? Attacks from the rear do more damage....not really original.
"Weaponskills that do additional damage vs monsters"- First time I ever heard of this, as their desciptions dont provide any info on damage calculations or anything. Again I dont really play melee though.
"Afinity with weaponskills and their damage on class vs off class"- Another reason why the system doesnt work well, weaponskills on other classes arent worth using over the ones you already have on yours besides the ones that do something extra (part damage)
"Class specific standard attacks with additional effects"- im assuming you mean the difference between something like "heavy" and "Light" thrust. I would hope that everyone knows the difference between these...
"Effective stat allocation"- Again Yoshi already said stats are broken, while I do my best to get the most effective stat allocation they really dont mean much. Im going to heal for maybe 30 extra hp with 140 mnd than a conjurer with 50 mnd. Im going to nuke for maybe 30 more dmg with 140 int than a conjurer with 50 int.
"Battle regimen types (and their additional effects)
Additional damage from BRs (combined with any of the previous in this list)"- Yoshi has admitted that this dont work properly as well. I do notice a difference in damage from BR, but they are horribly clunky and having to stop and wait for everyone to queue up is absurd, yes with a very organized group you can make this semi fast but your not always going to have that luxury and its very difficult to get this down without voice chat.
Some effects from BR like lowering defense is nice but the wasted time that 4-5 members spend in br kind of offsets that, and people like healers cant even contribute because you dont want to be stuck in br mode while people die.
