* Once you *could* reach 50, there were often as many L1's in Peregrine Island as L50's. Unsurprisingly, Broadcast in PI consisted primarily of "PL me" or "Bridge wanted" chatter. The "bridge" was the guy who was exactly the right level to max XP between the L50 and L1 (I forget the exact level)
If I remember correctly, you wanted a level-47 character to bridge, making the sidekicked character level-46, to maximize the XP bonus from level difference; if you were only sidekicked to level-45, you exceeded the maximum level spread in the team and wouldn't get
any XP.
* The kora fruit mission could be kept indefinitely for medium inspies (My I-1 main still had *that* mission too)
You originally got large inspirations from the Kora fruit, until the devs decided this was an exploit and reduced them to mediums; my Fire/Rad Controller still had a 'large cave' Kora-fruit misson at shutdown, too.
* When you had to unlock different contacts to be able to purchase "non-power 10" DO's and SO's (like end-mod, dmg resist, etc). It was also important to know (in the mid levels) to sell stuff to the proper contact(s) for the best prices if you wanted to be able to afford your next set of SO's. Oh, and the stores? They weren't shown on your map -- you had to learn where they were.
It wasn't
unlocking the contacts per se; it was getting them to 'friend' status -- the point where they gave you their cell number so you didn't have to keep running back to them. And this was because the
stores only sold the 'Power 10' enhancements at the bottom level (i.e., 15 for DOs, 25 for SOs); you either had to get the non-Power-10 enhancements from your friend-status contacts or tough it out until the next tier (level-20 DOs, level-30 SOs), when the stores would carry the full set of enhancements.
* Perma: Hasten, PA, armies of fire imps, multiple phantasms, were all *easily* attained on SO builds, and Ill/Rad Controllers were *the* AV soloists.
Going along with the 'armies of fire imps' was the drawback that you had to stop every time you zoned, went through a door, or up/down an elevator and resummon them, because they all died every time you got shifted to a new map
