The most frequent help I see players asking for is with raid bosses, and they’re asking for low level raids, in the early morning of a reset day. This came up often enough that I wrote a thread about it…
…explaining why high level players aren’t going to help with low level raids until after they’ve done their own high level raids because this would mean they’d miss out on their own rewards to do so.
However, Vanguard gives an option to do this, i.e. if you have any of your 5 charges left, you can choose whether to do a Vanguard run using a charge, or not using a charge. This means you could help out players with lower level Vanguard runs without using up any of your own 5 charges, which you can then use up later with your usual Vanguard group.
If the raids had something similar, i.e. the ability to help people out without using up one of your own 5 raid charges, this would mean high level players would be a lot more willing to help out players with low level raids, as it wouldn’t impact the high level player’s ability to get their own rewards later, e.g. reset day evening with their Warband.
