Scaling has been around for a bit. We've thoroughly tested it in other brackets and found it to be less than stellar compared to going to the cap for that bracket. Then you factor in the F2Ps who have significantly less stats than level 29s even with scaling, and you want to argue about how level 28 is all of a sudden going to offer this magical difference that makes it better than being 29?
I personally don't care if you choose to stick with level 28 or not. I'm just offering my opinion on the matter based on the facts we've seen: it offers no benefits over going 29. It's not like we haven't seen people experimenting with scaling in BGs since 6.0 or anything.
The biggest difference right now is that BoA scaling seems bugged. It looks like they're going up double the number of levels.
I started looking at hunter numbers (20/22/24/28) and these have been the stats on the BoA gun scaled up from each:
20: 9 agil, 16 crit, 41-77 damage
22: 9 agil, 15 crit, 39-74 damage
24: 8 agil, 15 crit, 37-70 damage
28: 7 agil, 13 crit, 32-61 damage
If you look at the slider on wowhead (
Upgraded Dwarven Hand Cannon - Item - World of Warcraft), the stats are scaling from 20 => 38, 22 => 36, 24 => 34 and 28 => 30.
All the other BoAs are following the same pattern (chest on a 20 scales up to 12 agil/17 stam/12 crit).
If it was working correctly, there'd be much less of a case for lower levels. Right now it's a lot more debatable though.
