Naaaaa I feel it's you who is missing the point lil' buddy.
The key TEN event (of which girts is asking for) is the main event of the year for each PP. Caly, RT, Ark have all provided theirs and the big items have appeared. Cyrene has not provided their keynote event. Now, this causes problems (aforementioned) in the case of incomplete armour sets. Cyrene needs (before the end of the year, and that's pretty unlikely now) to provide their keynote event.
This is what girts is asking for and it's a completely reasonable (and logical) request.
What you are apparently asking for is this event to be "dumbed down" so that every common nooby has a chance of winning... a piece of Chronicle TEN. A 10k+ armour piece. This is unfair (if you can't see why then it's beyond me).
I have absolutely no problem with events based around the lower skilled, with relative prizes. It is not fair to give top-end prizes without top-end competition. All you do is dilute the market, make the whole game into a gambling-fest and basically erode confidence in your top spenders.
You say MA are ignoring 80% of their playerbase with high-skill events. Perhaps. But what about if we change players as the counter and switch that to pedspend? I would expect a reversal of that figure to the nth degree - to the state that MA are catering for 99% of their turnover with these big events, and ignoring 1%.
Noobs don't give money (as much) into the system. Yes its vital for MA to capture and retain new players, but it's also vital they do not piss off / lose their biggest income. Noobs have plenty of missions, events, places to discover, etc etc etc. Veterans do not have this - they've completed a lot of the game, they are hungering for new items to discover/win and stronger mobs. This is what keeps the PE economy going, constant striving to be better and spending money to achieve that.
But of course, you're going to come back with the argument that NO! You should have a chance of winning the 50k item. Of course you should. You're speshhhal!
