Technically if u manage to get an amazing timing on ur lurk u can wall off ur enemies on the other side of the map and delay for a good 10 secs while ur team plants the bomb on the other site.
Thoughts??
your head is in the right place, delaying the rotate is very good, but think about it, sage can do those things with the team and offer heals and even more so, if youre doing it on a site hit youre going to get consistent value versus a lurk not always going your way :)
like on ascent, you dont need to go top mid and lurk and slow off cat, you can do that from a main with the team, haven, instead of slowing a link thru b as lurker, you go A with team and just slow spawn and slow the rotates that way and be there to help and heal
to add on to your point about lurking sage, this is actually a very doable strat that can be called, like instead of "lurking" you just fake a site with the sage, and both slow the rotates in and out of the site, like faking B with sage on haven is OP and applies your idea of slowing the rotates while also bringing rotates from the site your team plans to hit (fake B go A)
