Can I ask for some information on playing on another Alliance? It's becoming clear that there are much better opportunities for rewards in the Alliance section of the game than elsewhere, if you want to advance your team, and I'm getting bored of grinding the arenas for shards.
This is me:

I suspect that I'm neither an outstanding nor a novice player; and have some champions that stack up well together; even if they're stuck at 4/40.
I have avoided Alliance gaming before because I'm concerned about the time commitments being very different to solo gameplay.
Not that I don't have any time; but as a dad of two with full time job, I tend to fit in my MCOC gaming in bits and pieces of 10-20 minutes; with longer chunks in morning and evening, and very little during the working day.
That works okay for Event quests and arenas; but does it work in Alliances? To be an active Alliance member, would I be able to come and go like this, or would that drive my teammates nuts? Would I need longer blocks of dedicated time, which currently I would struggle to get out of my life?
If I'm making progress in a map, then go to work for eight hours, am I in the way? do I become a roadblock to the success of my team?
I'd like some useful feedback please - I am genuinely interested in Alliance gaming, but would want to be an active participant. It's clear that AQ and AW have strict time-related issues, so I need to know if my way of accessing the game in short bursts of time is a hindrance to me and potential teammates. What are the best ways of finding a group my play style would fit into?
I'm looking at some stuff on YouTube about finding Alliances and so forth, but thought I'd ask for some direct advice from you guys as well. Happy to have your thoughts.
