I'm a "Revolutionary" sub, and I bought an annual sub when they had the same price for the "Legendary" tier in Dec. There's no way I'm going to use the extra features, and I'm worried about forgetting to change the tier later.
I do have two domains added, one for my primary email and one for junk. I use a few hundred MB storage, with no chance of going over my current 15GB limit in the next few years.
