RIFT has many features that make it the best MMO on the market in my opinion and there are two more features that I would like to see added that I think would make it even better. First a little background.
These two ideas come from another MMO called DC Universe Online (this is not an attempt to promote DCUO, I am simply providing background so you know exactly what I am talking about) which I play whenever I feel the need to take a break from RIFT. I've actually been playing DCUO longer than RIFT and the fact that I still play both is a testament to how "awesome" both games are.
The first idea is loot locking. In DCUO once you have completed a certain part of an instance you become loot locked to that specific part of said content. For example, if I come into a Kahndaq raid on the third boss, down him then leave, I am only loot locked to the loot that boss drops until the instance resets. Which means that I can go back into Kahndaq with a completely new raid during the same lockout and down all the bosses I didn't down in the last attempt (plus the third boss again) and I am eligible to roll on loots from all the other bosses except the third one since I am already loot locked to him.
This would be a fanastic additional feature to RIFT as we would no longer have to worry about getting locked to an instance for an entire week or locked out of certain boss loot drops because of where we came into an instance in progress. So if I get into a fail HK run where the RL rage quits after 4-5 bosses and the group falls apart because no one else is able to take over, I would be still be able to join a completely different HK raid during the same lockout and still have a shot at the loot from other bosses while still being able to participate in clearing the content I've already seen that week.
Loot locking bosses instead of instance locking players I think is in perfect harmony with the new mentoring feature that is currently being tested on the PTS, a feature that I have tested and like.
The second feature I would like to see added to RIFT is an equivalent to DCUO's replay badges. In DCUO replay badges allow a player to reset content as many times as they wish (depending on how many replay badges they have) before said content auto-resests. For example, lets say I full clear the daily but I didn't get any loot because someone else in my group ninja looted everything, not giving me a fair shot at any of the drops. With replay badges I can reset all of the boss loot locks for that instance then run it again with someone else who is not going to ninja loot everything.
The main difference between these two ideas is loot locking allows access to all content during a lockout period but only locks boss loot drops that you participated in and replay badges allow you to completely reset boss loot locks.
I know both of these features work wonderfully in DCUO and I think they would be a welcome addition to RIFT.
