I genuinely also doubt that it's a bug, but if it's not it's fucking retarded and I decided to take the nicer option. Somehow I feel like GW2 is absolutely falling apart. Who in his right mind breaks LFG in such a way? Every halfway sane person would come up with block working like you described, but whoever is in charge seems completely decoupled from reality and utterly void of any reason. I can think of no other way how a mind can look at such a design and go "this is good design". So the bloke I blocked because he's a raging cunt at every opportunity now also ruins my LFG by virtue of simply existing. Amazing.
God have mercy on this game.
Oh. Gliding back. And I thought I did the smart by gliding forward. Well, that'll ease the daily.
