For completely new players absolutely. But there is very little meat to the guide. It covers something that is indeed important but really doesnt help any more then making people aware of the fact that they need to find the "critical mass" point of their char when playing against others. Its something you cant learn from a short guide. It has to either be a very VERY long one, or, and far better, actually playing and finding out what point you need to back off.
Again, if your brand spanking new to these games, may as well read it. Anyone whos older then 12, has played a game like this before or has half a brain wont be helped by this.
Id say the damage by skill list would be useful but it is incomplete and in some instances wrong.
Well here's a start on the skill list:
UB Spit - dot is over 10 seconds
rank 1 - 50 intial 450 dot (avaible at level 1)
rank 2 - 100 intial 800 dot (avaible at level 4)
rank 3 - 150 intial 1150 dot (avaible at level 7)
rank 4 - 150 intial 1500 dot (avaible at level 10)
Putrid flow 500 damage over 5 seconds (avaible at level 15)
That's argueably the most important skill to note when running away. I've gotten many kills from people who thought they could run back to base after being spit on. Especially rook players need to learn, you're slow you need to run back much earlier meaning missing a hammer slam normally results in you needing to retreat.
