The thing is, I remember the first transition from rhino to WILTOS, and we had to revert really quickly as it broke the server. Then after, the system was re-added and it felt really no different.
Now, let me put this into perspective for all the Rhino lovers;
Yes, it's great for fighting, the skill and learning curbs involved. And yes, it may be really for great for performance, maybe.
So, with that said, I have to list all the problems this will bring to the server, performance aside.
1.) It kills the roleplay aspect of the force powers, and people who focus on their force usage. i.e. Assassins, Sages, Sorcerers, Shadows etc.
2.) Unpopular opinion, but I believe WILTOS has more skill. You have to learn all these stances, hitboxes, timings, create your own fighting style that you enjoy using etc. Also, using your knowledge of these stances and styles to teach others who wish to play just like you.
3.) Running at eachother like special snowflakes head on is just stupid looking.
4.) Every trial will have to change in some sense.
5.) Also, possibly Jedi and definitely Sith will just degrade into nothing. Without the force powers, Shadows and Assassins become useless. No shadow strike, no cloak, no role. Sages, Healers, Sorcerers, as much as they are mostly passive roleplay, the force powers really assist in how they pay or grow with their characters.
6.) If dual sabers are gone, Marauders become useless, wouldn't really effect Sentinels but in terms of how the reputation system works, all sith would classes would become pointless, it would degrade into nothing but passive roleplay, not using any of their unique abilities to gain an edge.
See this as you will, there are advantages and disadvantages. Though this is just my view on it.
