Personally I think it's interesting to see how many are opposed and how many are for the suggested changes, quite a divided viewfront all together, personally I'm for the changes for a number of reasons.
First it should help players who haven't got much opportunity to enjoy the battle-station, there's a feeling that the BS's at certain Ranges don't run, so no one signs up and thus they don't run, this change shakes that up and that alone should help them run more often.
Secondly I've seen a lot of people complaining about how level 200 is so much more overpowered and the new resultant twinks are just going to rofl-stomp all the TL5 tower twinks, my thoughts on that are two fold, firstly 'Ha ha, about time' not very nice of me I know, on a more serious side of that argument, the twinking has gotten out of hand, it's far to expensive and the gap between twink and non twink is far too large, shaking things up there might annoy the twinks but the rebalancing is going to do that anyway, at least I would hope so or it's in vain. Secondly if the 200 toons were so overpowered then why aren't there already a legion of them rofl-stomping the TL 5 tower toons?
I think removing the lower level towers would be a bad idea, personally I'd prefer they removed the PvP level restrictions on the towers so a 220 toon could attack a level 10 tower field (that's not to say they could attack level 10 toons in that field however). That would forever remove the problem of 220's ruining the TL 1-5 tower scene because it would all be TL 7, if the TL 7's cared about the fields in question.
But then I'm also of the opinion that anything before 220 is part of the levelling experience and that permanently stopping a character at a level before that is a sign that general game balance is broken.
It should never be a disadvantage to gain a level.
