Improvements for LvL20 Random Arena

Well then, i searched a lot, but there seems to exist no recent topic about this, so i try to bring it to attention again, because it really pisses me off:
Since the Faction System was introduced, i play the LvL 20 Random Arena a lot. The problem is, that it is getting less and less fun. because you can easily spend half an hour befor you get half a decent team. Why?


First Reason: The LvL-Cap only works 1-way. LvL10-16 Chars with like AL30 who think they can win sth but only ruin a good game in the LvL20 arena can join easily and do that frequently!

Solution: It is not easy to fix, as you can argument, that also a lvl19 can be nearly as effective as a full pvp-char, and you cannot forbid a lvl16-19 to enter ANY arena after they have outgrown the shiverpeak arena.
However, the fact, that you can access the lvl-20 arena from lion's arch does not help at all to decrease to number of noobs there.
So I see 2 possibilities: make a lvl16-19 arena to split it from the lvl-20-pvp-chars
OR (if this is not possible)
move the entrance to the lvl20 arena at least away from lions arch and lets say to amnoon!


Second Problem: Stupid noobs, who leave immeadiatly after they fall in battle, or - more common - leave in the "Craig" arena, after their team is like 3 kills behind.
Consequence: the enemy team has an easy fight (or no fight at all and a boring 3 minutes until the next round begins)

Solution: A faction penalty with lets say: 200 faction if you leave while still being alive OR in a arena where you are rezzed automatically and ~150 faction for any other leaving in the arena.
I hope this will prevent ppl from giving up to fast and ruining the game for the rest of the team.

Suggestions, opinions, critics?

Regarding the underlevled people in the random arena, I would suggest this: create a new random arena for ascended characters only. Of course PvP only characters would be admitted also. Now you know that even if they are under 20, they've at least been through the desert, have access to Forge armor, and elite skills.

yes that would be a good solution for the 2nd problem.
the only thing i might see here, is that anet might say that then there are not enough unascended lvl16-20 players to fill an own arena all the day

Or add in something to do besides fighting. Smashing chairs over people in mission zones. I'd take that. Just something.
