We hear your frustration. The monolith system was definitely designed for starting it right after the campaign and we did not sufficiently account for players wanting to play with existing higher level characters. There is also understandable confusion from people assuming that the whole monolith is level 55 when in reality each timeline is a different level, and only the first one is level 55.
We’re considering the following changes for a hotfix to address this
- Remove the experience penalty for being a higher level than the zone for all zones above level 53.
- Make the quest echoes in the first timeline show up much earlier, so that players can more quickly progress to higher level timelines.
- Reduce a source of unintuitively high damage in the first timeline’s boss fight so that players are less likely to die to that boss.
