No way. Activity shouldn`t be removed by any means, as:
1)Its designed to keep a race a bit fair. In current state it limits things a bit too much ,but still limitations is needed.
Being 24\7 active should feel rewarding, but still, imho, there should be some limits at which the gap between "casual" players and "hardcore" players can grow. With current IMC settings its a bit too narrow, tho. Situation where "hardcore " player grows 4-5 times faster (in terms of vis income\level\ questing progress\etc) is normal, while 20x more growth will simply scare the "casual" players, which can run from GEEU to Andromeda.
2) Its a core feature which can make many things unstable if deleted. Not only Nimrod, but also some events and stuff (dunno if Andromeda staff have access to events, but still) is also limited by activity.
Possible solution is to increase the amount of activity you can get from different sources. For example:
1) Increase amount of times that you can recover activity at Nimrod. From 1 time per day to 3, for example. Can be hard if its hard-coded as boolean by IMC, still.
2) Increase amount of glyphs dropped. Like x3-x5.
3) Change some daily quest` reward to Karin`s potion (that restores Activity). That`ll encourage ppl to use some daily quests that`s currently counted as "zero profit". Possible options is Kielce daily quests (as its mainly used to grind artifact parts, which is limited demand for a players, and SBernelli is rarely a desired reward as the amount of grind to get her is terrible. Changing some rewards (like Victor daily for materials, Boy of Kielce, Hotel promotion, etc) to Karin`s potion will make players activities more diverse.
4) Increase daily limit, so you can get more Activity from AFK leveling for a night, recover more from Nimrod& potions, etc.
I suggest going for 2 and 3.
