hmm
I think with 18.7 the terminology of "grief squad" has shifted somewhat from 18.6 - at least for me.
in 18.6 a grief squad is 2-6 players.
in 18.7 a grief squad is 12-18 characters.
I saw evidence of this many times this week. Meliz and her box counts as 1 person and 6 chars, but alone she had a hard time taking out 1 of our 220-230ish towers before getting killed or forced meep.
The result is that if you want to grief you actually need a few teams to get enough DPS to be able to take out a tower before a forced departure.
This system worked remarkably well for AP+DI.
Basically, me+wont+soul were able to grief hard, continuously for the week leading up to the clan Tl7 takeover.
Omni are trying to do what we did, but clan is just far more interested in continuing to PLAY after the grief/towerfall, and it seems clan are more interested in making PVP on defence than Omni was.
An 18 person grief squad could take out a CT... but it won't be easy. I don't know what the HP is on the QL 275 CT's are, but I'm damn sure that the HP rating on the 300 SCT's/X11's are enough to make most people's heads spin.. iirc I think it took about 2-3 minutes of fighting/spamming damage to take down a 300 turret.. and I recall we would always debuff them to slow their damage on us while fighting. I also recall that we lost a lot of people to the turrets while field cleaning.
The CT (even a 255) hits about 4x harder than the 300 turrets. the CT kills you in 2 hits, so it's like tanking Xan in 12man... that's basically like continuous agg management/healing. I'm positive a 275 CT will require an enf, debuffs, and a keeper in team+a doctor+others healing - that's not impossible for a 18 person grief squad, but it would definitely require more attention than just q+spam damage like in 18.6.
More evidence of this: check the number of attackers Omni had when they took out our CT in PW4... it's almost cringeworthy.
http://towerwars.info/c/overview.php?d=5 42 people!!!! mind you, that's partly because there was such staunch defence, AND the tower timer was getting dangerously close to going cold so Omni probably drew people from everywhere they possibly could to boost DPS.
I just remember in 18.6 I could take PW4 CT with just my box and probably not even need to cast a heal for the entire fight.
