The only reward that matters in PVE is the 25 CP. However if you don’t commit to playing for roughly 3-4 hours per day, then you can’t get that reward.
I would highly appreciate if in addition to the current pve, there was a new, slower PVE that lasted much longer, so you could hit the reward on your own time, playing less often but eventually getting there.
The reason why the current version is a problem is because due to the high amount of time required, I just won’t bother to play pve if I can only play for a few nodes per day, because it’s just not worth it.
Which is actually fine, as now when I just have a few minutes available, I’m playing other games instead! Other games where I can make significant progress by just playing for a few minutes per day… whereas with this game I gain what, 500 ISO? Which isn’t much when I need 360,000+ to champion a single 4*. Games that do include some timer-based goals, but they also have a large non-timer based section as well, so you can play it at your own pace, and it’s actually relaxing instead of extremely stressful to play.
And “play-at-your-own-pace” doesn’t really count for the new pve system where you still need to play for 3-4 hours per day to hit progression and 6-7 hours per day to hit top placement.
