Did a run now with this teambuild:
Clocked first floor at 6 minutes, and I would like to say I did second floor in 14 but I RED ENGINE GORED ENGINE GORED ENGINE GORED ENGINE GOed up rather bad ;p My inventory was full so I didnt pick up the boss key (adding ~50-60 sec time when I had to run back and get it) and I didn't think when running in to the boss room and shot evas at once pulling em all before I even got team in to a good position. Wiping and then I wasn't close enough to the shrine near the boss room so I had to run from all the way back before the Boss key room (adding a bit over another minute). Still completed in 17 minutes though and could've clocked it in at 14 if it wasn't for my own mistakes.
I'd like to call it a shitty run but I did get a froggy so I don't think that is allowed xD
Anyhow, my point with this is that Bogroots is one of the hardest zones for a team build like mine. I have almost no heal, only a single signet for hex removal, only a single skill for condition removal. Which means my team can very easily get pressured out.
So in my oppinion your team build can drop a ton of defence and still do a really good job. Grabbing a ST such as Relyk suggests is just plain unnessesary. Grab a smiter instead for more melee damage (+good hex and condition removal)! And drop Hex breaker on the mesmers, you don't need it.
PS: You do a great job in how you actually play though!
