My question is are the high ranking acknowledging when a newbie is trying to deliver daily and how hard is it for them to reward such newbie with merit?
Merits are given out subjectively and aren't dependent on whether or not you are a newbie or legendary. In some parts of the forum they are more a popularity contest than reward for good posts.
Merit givers hardly ever go looking for quality posts in the various campaigns etc. Just be yourself and make quality posts.
