I call it a paid Beta because we are asked for our feedback.

Usually when a game releases that is full retail ready to launch with no major screw ups, you just get add-ons, expansions w/e you want to call them. Not full blown "Player Polls" to tell the production company what's wrong, feedback about new battle systems, server lag, Wyvern no Wyvern, jump no jump, jobs or no jobs, PvP or PvE, LS admin functions, search features, chocobo/mounts,new leve system, new crafting system, new recipes, constant balancing of current jobs, ... shall I continue?

This post, like the one saying "server merges are bad they should do transfers" and as has been mentioned here, semantics and your own POV and terminology. Wrong or not, asking people to not say it's a Beta is like asking those who still call Characters Toons or levels Rank to stop ... at this point, they're just words and you know damn well what that person meant to say.
