As for your third question, DW is really fun! There's a lot of things you can play around with, since all the unreleased Dream World abilities are released, and there's numerous strategies that are all very viable. Of course, sand and rain are still quite prevalent, especially with Excadrill and Garchomp available, but it's still a great metagame. Blaziken was recently banned, so that'll be sure to make some people really (un)happy :P
I like to test out a lot of new shit, for example, I made a meloetta team that worked out pretty well :D
Haha, well the first couple analyses are always gonna be rough, but you'll definitely improve over time. My first couple analyses were terrible, and I'm quite ashamed of my writing, looking back. But I did improve, and then there was a point where I was churning out 3-4 analyses per week, with good quality to boot haha. The GP team is here to help you with grammar issues, so that shouldn't be too much of a problem unless your writing is on par with some of our more terrible analysis writers..... I won't name names xD
lol nigga i quit NU after like 3 months hahahahahahahaha xD
actually i pretty much abandoned C&C lol
DW is more important to me these days, but it's so slow since all these dumbasses keep leaving their analyses sitting there for months with no work -___-
