Is it now ? Lowbie traders should be subject so some nerf or balancing, but at tl7 taking away drain power in comparison to an enf who got another stun nano/perk w/e and a shade that will be able to sneak mid combat, these changes aren't really welcome.
Not to mention that with some effort, most pistol users can perk under one drain..if they did before, they sure will be able to now..all this while trader def is still at a point that you cant evade anything without draining it.
If the line cooldown will be more then 4s, this will mean a utter nerf. It would actually be worse then having 4s recharge. Before you could cast a drain every 4s on multiple targets, now you wont be ?
Not to mention the fact that a trader can: drain person A, attack person A, drain person B when it attacks the trader - but person B just uses the Health and nanorecharger for insta removal.
Get this - the drain is removed before the traders nano recharge is gone. Amazing aint it ?
