I am a new player in Europe, who unfortunately cannot easily make Paypal payments and i have been enjoying the game on trial account.
Today i noticed i was not getting XP or stats increase; the reason was that the action i was performing was of a capped skill (30), neither was the action counting. I have confirmed this is intended feature with game guide.
I would like to suggest that the full limitations of trial account (and i expect also unpaid account) are properly explained and made available for the purposes of clarity and to avoid frustration or disappointment to new players.
