Cloaks are also fun for the players using them, ever consider that? Some say how dare a few trading runs trump your pvp practice? But some have RP investments and don't always feel the should be EASY bait for new players or people that are only here to PVP.
As I'm sure you have found out, all Cloaks can be CD'd, and interrupted during the charge process. They are best for getting away when you're enemy is distracted or you slip our of range first. I'm not even sure what the charge time on a small cloak is, but if its still 3 seconds, thats your first problem. Small cloaks get longer cloak time and can disappear pretty fast it seems. The other cloaks give more than enough time to CD if you're in range and are paying attention.
Cloaking is a part of disco, its not vanilla anymore. You'll all get your chance at a mountable CM (in some form) in the future it seems so relax. Cloaks can be used by everyone, so if you're not using one and are complaining about others doing so, maybe its time to compete instead of complaining. Its not PVP death, especially if you escape in something other than a light cloak, its usually just as important a survival skill to know when is a good time to use it, like bugging out when you see your chance in any pvp encounter. In the end if someone escapes you to flee, cloak or not, you won that fight, be happy. So what if inrp you might fight the same enemies in the future.
Remember the counter arguments, what's the point of having made cloaks usable for years on this server if everyone complains when they get 'used against them', meaning, someone used the cloak for its practical applications. They should be able to be used for escapes, ambushes, espionage, etc and its up the the players to figure out the rest, both users and non users alike.
