I know that PvP/LD suggestions are the most frequent and least popular topics ever, but I'm going to give this a shot.
After seeing this topic: http://forums.spiralknights.com/en/node/78381
I took all the posts into account, and drew a conculsion: we need different gear for PvP, a different GUI, and a different battle system. And less lag too. I'm not a very hardcore PvPer, but I do play the occasional BN. I've only tried LD once, and that's because my computer chooses to use the restroom until I stop playing LD. I do know how much my fellow knights enjoy LD however, and that PvP has a lot of SK potential. But as stated in the other post, PvP in SK is extremely unbalanced, and specific items means that you win. A lot of great PvE items are useless in LD. I acknowledge PvP is not LD, but LD is after all, SK PvP, and in order for a PvE game to have a PvP function, you MUST change the game heavily. Different armors and weapons would need to be introduced, or maybe you wouldn't event choose a loadout. Different classes are assigned weapons and armor, in order for the game to work according to how the class dictates. But I'm sure that everybody would prefer to keep their customization. There could be seperate LD shops, and and LD auction house.
If you like what you see, leave a +1. See you later!
The only comment i have is to keep our current lockdown and create a branch off it. So we have 3 game modes in our pvp coliseum signup.
