Ok, here's what I think:
Dylan Hsu didn't write any pre-made strategy (I myself prefer to keep distance from them and usually just play with my friends because they don't use any of those "recipes" - there's no point in playing like that as the game reduces it depth so much when you do that), which is a definetely excellent thing IMO. Then some people think that it's missing from his "handbook" - wrong.
Even if he wished to write pre-made strategies and fast-win recipes, he'd need to redo that every new version because of the balance changes. He himself said that he wanted to give an overall background for people to play in a more intense way. This can be appreciated (but I still can't stand his attitude, which is really childish IMHO).
Anyway, balance shouldn't even be mentioned here, and I think Dylan would've included his own opinion on "what's the best weapon to race for" if he wished to enter in this aspect with his "handbook". Zarel is probably very stressed already (with good reasons - obvious for anyone who looks at all the forum's boards and posts) with people whining about cannons, or even people whining because the developers make balance mistakes sometimes. What I think about those people doesn't matter to conlcude my opinion of what's going on:
Dylan wished an general overview of what he thinks players should do to start trying to play better. Some people think that "best weapons to race for" fits here (really doesn't, I think), and this guy mentions an outdated strategy to make things worse. When icefire explained that, saying that cannons are overpowered now so that's the best go if you want to take advantage of the balance issues, Zarel probably thought of all those people complaining about that, and let out a "please stop".
No
big deal IMO, just a somewhat inconvenient "combo". I'll now do my part and help keep the topic on the line
