Same goes for bursts. People talk about it publicly.
The simplest solution I see is to 'oblige' some people to man the sparring grounds , since it is the main location where this problem occurs.
I suggest LHO's since, not only that SG staff are rare nowadays, but also because the sparring ground is pretty much like the PC, where beginners start learning the game and ask alot of questions.
If you see spoilerific text on the chat, pm the person that he did something wrong. If you see a spoilerific conversation developing, stop it. If someone convinces you to teach him a spoiler, remind him the rules about spoilers. Its as easy as that.Pretty soon, this thing will be solved. Problem is, some people don't have the initiative react at these situations.
About some MP3s being powerful and all that, take it this way.
First, MP3 is exciting. Everyone has the same exp limit, so they all have the shot to being the top. Tactics determines the strongest. Same goes for MP4. As the game develops, more tactics are also learned, therefore more opportunity to make stronger MP3 ALTS. Thats why MP3s get stronger.
Second, as Chewy told me the other day, 'some people tries to own the lower MP levels because they think they won't last in MP5'(Or something like that)
Unlike in MP5, having the right crits in MP3 will basically sum up the whole equation of being strong. (This has some SCARY excemptions, though) So if a person has access to strong crits and thinks he won't survive in MP5 anyway, he settles in the lower MP levels to redeem his and his drach's proud arses.
