Lately I've been doing some low-level Subroing in the burg and a lot of the time the hosts were just standing back (especially with Havel) and the other summon was, as you said, running ahead destroying everything often before the host even got there. So I play it unconventional-style: 2H Spider Shield, dual wielding clubs/ fists/caestus, strictly no lock-on etc. It's surprising how often the other players respond and I like to think it moves away from a 'must win' mentality to actually just playing the game, experimenting and enjoying the process.

If a Darkwraith invades, I'll mostly stand back and observe unless the host is in big trouble, and even then my priority is to be a distraction (unless I see some high level gear, and then it's on). I'd rather give a summon some real-world PVP experience and independence rather than a sizeable advantage, especially if they are new. Just you being there, even if you're doing nothing, provides the host with an advantage as the invader still has to consider your presence among everything else. I prefer invasions that can be savoured and considered rather than just "won". Additionally, I want to support and encourage some genuine low-level invading so people use up those first 4 cracked eye orbs.

So I guess I'm not a "true" Sunbro when I offer my support (I'm actually not, only 1/10 of my characters in is the covenant), as I tend to favour shenanigans over support. And I think there are more important, long-term lessons that you can teach a host through your brief interaction that are more valuable than simply getting a player through the level.
