As in asked for by pretty much every single TLP population from Phinigel onwards, and because of precisely that reason convenient? Yep, maybe you have not visited the forums much over the past 7 years because it has been a fairly recurrent request.
Well, 10 weeks isn't too bad. With the low level caps, boxers should be able to get their box characters leveled up individually in the meantime if they want without it taking too much time. Speaking of 10 weeks, maybe this server will be one where the population stays high longer. The 70 era is responsible for a ton of attrition, and that era is flying by in a blip on this server due to the combined unlocks.
Well yeah! That's exactly why removing truebox is important: there's fewer people around, so most players that single-boxed the early eras start boxing so they can get stuff done more easily.
