Best missions / quests to save up EXP?

What are the best 10 things to save up for leveling to 116?

Getting to 99.999% and not dying
I have been saving up my collection item dispensers, not sure if I want them to go to AAs or XP, depends on how much xp it gives.
Doing overseer and saving up as much as you can in the rewards windows will also help. Other than that, I believe CotF and TDS gives xp runes you can use later.

Getting chores done around the house before release, tbh.

collection item dispensers and tov mission achievement rewards if you haven't collected them yet

Given some of the level requirements/restrictions for AAs I've seen on the Beta forum, using whatever you've got to hit 120 first seems more productive than holding dispensers for the AA reward.

Overseer 24 hour Research completions, 10 in the Reward window, 5 sitting in the overseer window ready to claim, if you are level 5 in this, each one should be worth up to like 5.4% regular exp (if Purple/Elite tier task Crit Success), if you have monthly dbc you don't use or care about, even though paying to insta complete quests results in like 4x higher fail rate, to fill out the rest of the 5/10 completion cap (and maybe 10/10 on next overseer 12 hr quest cap reset)

If you haven't completed any previous expansions collections, bank as many of the Overseer Collection things to get those all checked off (each one should be worth 2% regular at 115)

That is probably what I am going to do.

I use the collection for aa's without having to leave the baz lol. Those raise 350 tradeskill mastery aa's get real expensive last rank is 65 aa's.

Generally speaking, the XP rewards from quests are far more than the AA rewards for them. Merc/partisan in CoV are 3% XP at 115 but only 15aa. The time it takes to grind 3% XP is substantially longer than 15aa. Overseer does not give AA. Generally speaking it is best to keep the AA slider on 100% and get your XP from collections, overseer, quests, etc. Claiming AA from collections is a waste unless you are at 99.999. Even then, unless you are doing something with them, like the TBL evolvers, it is best to bank them until the next level cap, then let them plow the grind for you.

Buy Redbull and Cheetos in bulk. Sit in front of computer for hours and hours. Ta-da level 120.

Insert Redbull because Jolt cola is no longer sold =(

The real tip is: do progression, put all exp into leveling, get to 120 then you can work on AA.
Once max level AA will come super fast. Also remember you have a full month ( about ) to get raid ready.

By completing shiny collections with Overseer you can receive AAs.
