First of all, I'm rarely on the forums. 5 posts (playing since pre-launch) to your 1000+. I did a search on the topic before I even posted, and nothing about participation came up but my apologies that I didn't check in with you personally. Second of all, I don't see how I, a single player, am responsible for not just one but two servers mostly quitting WvW. And yeah, mag had people on all four maps, and groups defending towers/watching sentries and camps. Not 1-2. 3 or more. I can switch to a non-support build for solo play and kill enough NPCs in between the 3 veterans spawning to maintain participation but that's still playing around a design flaw, and it's not just about me anyway.
On the flip side, when you have max participation, you have nearly 10 minutes to goof off when you're doing well (or at least your team) before you need to tag something again (and back to goofing off). In its present state, participation IS easily exploited when a team does well so the developers (is there some other way to reach out to developers?) might want to consider whether the participation system is working as intended. Worst case scenario it can be feast (if you cheese it) or famine.
