Lockdown is extremely difficult to do well in unless you have double penta, and a bunch of really good UV's on a chaos set. This means only very rich (mostly paying) players play lockdown, and players need to grind like crazy to get those good UV's so they can do anything useful in LD.
Let's be honest, pentas aren't that hard to get, so no change needs to be made there.
So to fix this, make the chances of getting UV's (good ones and all) higher. This would make it easier for people to get their own UV's, and also make the value of items with UV's on them lower, allowing them to be more accessible to players who aren't dripping with crowns and energy. This ultimately leads to a better LD experience for everyone, as the player-base would be larger, allowing people to find a game quicker. It would also mean that once in a game, the teams would be more balanced; the game becomes less about who's spent the most time and money getting ridiculous UV's.
Fin.
Thoughts?
The nature of lockdown is fundamentally flawed, and this change won't fix it. The ability to have gear (cough kat cough chaos cough) that is much, MUCH better than all other armors in LD makes it unreasonable for the average player, who won't have access to these two specific armor sets.
