I have a Zepyros One as well. I tend to use it in the colder months.
My other tent is a Marmot Pulsar 1P. To pitch the outer first is easy, I bought their footprint, every pole slots in exactly where it needs to go, then whoosh, on goes the outer, in speed terms Marmot have helped by the 'instant' securing clips they use. I know my tent so well I'm sure I do it blindfold! Before I bought the foot print I used to use a couple of pre-measured strings with loops in the end, which worked almost as well.
In my experience of my tent, if its raining in the morning, its easier to keep dry whilst dismantling than my Zepyros is. At least I can stay under a dry cover whilst I pack my gear. Due to the smaller internal space and sit up space in my Zepyros, packing my rucksac inside my tent is very difficult for me, I'm 74 and no longer that flexible a person. So in my case I find that with the Zepyrose I have to be in the rain most of the time when getting organised.
Personally I wouldn't say that my Zepyros is any easier to pitch in the rain either, just a bit different. The problem you pose is not something that I am personally bothered about when deciding on what tent to buy.
