1. Beggars can't be choosers, eh? If the population is too high, there is bound to be situations like this occurring. If it bothers a player enough, they will do something about it. If not, they won't do anything (except maybe look for other alternatives).
2. 5 minutes to wait versus moving over to the portal and clicking it...
3. Noticed you didn't say anything about 3, so I take that as approval.
4. There are plenty of options for players if they don't want to experience what is described in the OP. Teleportation powers are one of those options. You did not come up with a reason why this is not good alternative.
5. You used quotes in that one, but those aren't my words, so I am assuming you're responding to someone else... but then you quoted my post. Are you confused about something here? Definitely don't understand what you are saying here.
Moving the arrival point or imposing an intermittent repulsion field require time and effort on behalf of the HC team, my alternatives do not. They put the onus on the players to use what is given to them to solve their own problems.
