I have a "simple" rather selfish suggestion.
Give anybody who currently owns a BAB, ITD, ITB, or any bomb from the shard bomb line enter the test server
This would cause one, maybe two things.
1. Draw the people who would be affected by these changes into the test server. (As of now, I hear there are hardly enough people to start a LD game)
2. Maybe increase the popularity of these bombs; Even if people get them just to test them for a short while.
They want players who pay "regularly" (about ten bucks a month or something) to have exclusive access regardless of their competence in whatever is being tested. What they should do is create a roll list of players they know are competent in whatever they are trying to test rather than letting any moron use the new stuff to not give feedback on it. This would mean picking "favorites", though they would be the people who should be testing to begin with because they know how bombs work. The main problem would be finding these people.
For the record, court, and jury; I support that players who are competent in the field which is being tested, in the current example bombers for the new Crystal lines, but only if real bombers are selected. Not people who take Shivermist in for Vanaduke and never use anything else. I mean the kind of die-hard-I-am-going-to-use-this-even-if-you-whine-so-shut-up bomber who can take a Graviton into Candlestick Keep and find a use for it; for those who already know what it is you are probably that kind of bomber. If you found the use for Big Angry, though impractical due to the excessive animation, you are probably that kind of bomber. We are a miniscule minority due to the intelligence required to play this way. Why are we not specifically tasked to test what we are going to use regardless?
