As thousands of people have stated. Turbine is a business. Not to put a bad taste in your mouth, but this situation is similar to DDO itself. If you're VIP, and you can't pay for the next X-months, should you be entitled to everything you had? The sad truth is that is not how DDO works. You loose all access to everything you had from VIP that you didn't purchase. All the slots, shared bank, races/classes, all of it, unless you bought points outside of your subscription, then you get to keep the first 4 characters on your list, but even still you may not be able to play them due to race/class that you didn't unlock/buy.
The Catacombs is of similar design, there are like, 5-6 dungeon doors. It's not hard/challenging unless you're level appropriate, or soloing the whole thing. A guess pass (90 min) may not be enough, since you have to talk to the bishop like, 4 times, then fight him. The only real benefit there is that you get the reward from a guy outside.
Turbine has to make money. All I can say is buy them 2 more passes so they can get another full run in. I'm f2p, and always will be. However, when I get disposable income, I'm gonna start buying TP packs and buying content. Starting with 1 shared bank page, 1 character slot, and all the low level adventure packs. Then I'll work on my first drow, or vet character, if not 32 pt. I don't remember what comes after drow from favor.
OP,all I can say is that if you get the chance to spend money on DDO, get enough to buy Delera's. problem solved. heh. If you're friend buys you the adventure pack, then they should be friends enough to buy you another. If not, they actually are wasting TP. No offense.
