Definitely. Any character you have that is 'behind' another in progress on the expansion feature should get a boost - not just the 'catchup' mechanic, but an actual boost / benefit. For example - if I start doing a new covenant on another toon, the quests should easily double the amount of renown per quest reward and drops of anima should start out at the higher levels that my main is getting. I've already spent weeks/months grinding just to complete the campaign. it makes not sense to do the same long grind 4 times. You don't get any leg up in this manner since you'd only benefit while you're 'behind' your main, but it would make a world of difference and make things much smoother/worthwhile to level alts.
