Judging by what I've seen of the population lately, this is becoming an issue. Everyone can get anything they want in the game, and they have, multiple times now. Hell, even I have about two pages of 50s, I only had 2 back on Live.
So stop.
Don't farm, or do too many farm-like activities - Peregrine Council parties for example. It's like Halloween (and ToT at the hotel): it can be fun to have one big candy-orgy of excess occasionally, but eating like that all the time makes your stomach hurt.
Don't rush through anything, no speed runs.
You can start from a MIDS plan, but then throw caution to the wind to do what sounds fun. I usually hate playing with toggles I can't run till I'm like in my 30s (Endurance issues), like Tough, Weave, so out they go! I always find I feel very useful when I get to use a rez on a fallen player even if it doesn't happen too often, so who cares if I can't set-bonus myself into the stratosphere with it. Take the rez, placate, group fly, anything you want. Supercharge your flamethrower so you can use it every group if you like it.
Weird builds are a fun thing to sink your teeth into, if you can find one that appeals. I've started two semi-petless Masterminds out of sheer cussedness because I like the idea of wading into combat with two lions at my side, and I am very re-invested for now.
Lead teams if you don't.
Write MA arcs, play MA arcs, there's tons of great stuff out there. Writing them will be very frustrating and time consuming believe me. 😃
