Being relatively new to the forum, I used to just hit anyone worth lots of points on the way up. Nowadays, if it’s a name I recognise with a smile, I tend to skip them. Having said that, there are a fair few of you with 270 X-Force/TGT, and I mostly just cower in a corner while I hit skip in that case.
It does get tempting if you’re worth more than 40 points, though. 
There’s some good advice here about avoiding hitting people in the middle of a hop, though. I think I’ll adopt it.
I recognize names here now that i have been trolling the forums more often. I actually quite enjoy some "friendly " opposition. I get hit, sniped, and even asked if im shielded by other members before they take me out. So is all fair in versus mode. I’m a competitive player that is in to get the best score i can. I dont take the game personal, but i do project some smack talk to my adversaries occasionally. More than anything i enjoy being part of the community. I have my allies and my opposition waiting to take me out when FR3L4NCER pops up in thier Q. Like i always say… “it’s only a game.” Please dont take it personally if you take some hits, but do feel free to comment about it… especially if it was delivered from me. Cheers!
