I don't need to watch your video to understand people using Bottle of Rum for a heal, i've been doing it myself until i got FoM flask. What i pointed out was that you listed "easy" heals to strenghten your argument but used a one with loooong cooldown and shared timer, and Store-bought pots.
I like to play aggresively, not skulking all the time in the back of the group, that's when i can feel i'm contributing more to the party. Because when a rogue only assassinates with a occasional swing here and there, a party would be better off with some other class instead. And there you go assuming things again. I've never said i'm playing in LD. I've never said i'm having agro/healing issues often. Hell, i'm even still wondering whether, if quickened scroll idea went live, i'd make an investment in APs to use it, cause for me cocoon is clearly better and faster and i'd rather have other things from acro/harper trees. I'm not giving advice in this thread solely so that my rogue benefits from the possible changes, i try to look at the problems from less-geared people's perspective too.
Yes, i know most mobs check their threat list every few seconds and switch targets according to it. That's not the point. You can't seem to grasp the fact that you don't only fight 1vs1. Unless you do? If you have only one mob on you that's not a problem. Anyway, it's not solo fights that are tough for rogues, it's bigger fights with archers/cleaving mobs.
I'm still toying with Poisons chain, 6 APs for single target +5 damage and -20 MP with an attack requirement is a rather steep price. Especially, when -20 MP is only really useful in fights with bosses or 1vs1 big hp bags, and depending on how champions are coded it might even be only around 8-10% damage reduction on them.
I'd like to applaud your confidence and/or foolishness when you say that you'd stand in one spot and take a beating while scroll healing in end game content. I know i wouldn't do that.
It's just funny that you admit you are using cocoon and see it as easy button (which i think all agree it is one), but don't see it ruining "your playstyle" (which is jumping out of combat, healing, jumping back) while the very idea of quickened scrolls (which would still require 2 more button presses and more time to execute) makes you shudder.
