The above MB hunters are absolute trash. They'd be more effective if the guy simply ran a single 24 hunter. Also, while you won that game, you all died a lot, and frankly it didn't look like much fun to me. Anyway, random games are random. Some are great fun, others boring, others just painful and not worth your time. Working together in a premade against randoms sounds boring to me. Against another decent team, sure sounds good, but stomping random noobs is kinda pointless.
With Navydew, if they sucked as much as that guy, or the 9yo from Bleeding Hollow, then you don't need any tactics. They also don't have healers. Three F2P hunters, all geared and with decent resilience, all healed by a 24 resto shaman, good luck using "tactics" on that. If you want to beat Navy at WSG, then you need to avoid them. It's the only way. I've capped a few on them, but it's not really worth bothering anymore and I usually just leave. The same applies to AB. Avoid them, be aware of their location, and cap behind them. As for Spirestone, it depends how many of them there are. It's easy to stomp one or two of them, less so when all ten are there, healing and running back to each other for support. Usually I just blow CDs, take one or two out, and then leave.
F2P is worth every cent you pay. Like anything in this game, or life generally, it depends on the people you're doing it with. You'll find all kinds of people here just like you will anywhere else. Some you'll enjoy, others not.
This makes me laugh coming from the guy who OMFG RUNS when you get hit with anything. I get it , I get it, its how you play and to each their own =)
