European Qualifier Discussion - 2013 and onwards

What if a team can't make it to enough NS events to qualify (financial, or restrictions on holiday time)?

It's 1 spot. To reduce the amount of teams in the qualifier. If it's announced in advance, then it's up to that team to decide on their priorities, and make their choices based on that.

What if teams resort back to their dynamic line-up nature

Then they lose the automatic spot. 2/3 rule.

What if the Euros organiser distributes spots differently next year (to cities/regions/etc)?

Then it doesn't apply any more.
