The ranking seems a bit weird to me at the moment, a friend of mine in another server is 1950 points and top 40 whereas I'm hitting top 50 with 2750 points.
This would be fine if arena tiers were based on being in the top X% of your server but when it's sat at 2600 points required to hit Silver Lion, how is he ever going to get that rank, or anyone in his server for that matter. - His server is essentially locked from buying Legendary Scrolls and Heliote Dice from the PvP exchange.
A simple suggestion would be to have a maximum amount of points players can be drop from a defensive perspective per day, 75 points for example. This would make players feel better about leaving a 1 man defence without dropping ranks so we can all farm points throughout the week then set up a defence to make a push for ranks later into the week.
