blablabla confirmations, toughts etc. here is the info about 71+ arenas.
1. After you ding 71 you cant invite to the team and you cannot be invited - thats CONFIRMED INFO.
2. At the season end you will most likely be kicked from the team or lose members ( unconfirmed, but many ppl were saying that)
3. Good things that you get at 71+ :
nifflevars, good for frost DK or enh shaman. or maybe as a 1-hander for a tank.
new spells like cyclone, wings or mass dispell and old ones at higher rank (more powerful)
engi ilvl200 head
much moar stamina
few talent points
4. Bad things that you get at 72+ :
Stats scaling- hit, resil, crit, haste. uhm maybe some other ones that i forgot already. you will have almost no gear improvements and with the same resil/hit/crit/haste ratings you will have like 1.3x lower those stats PERCENT.
You will need a lvl 70 "inviter" in the team who will invite members to it
How-to:
1. find partner(s)
2. at lvl 70 create a team, invite them there
3. invite a lvl 70 that will stay in the team.
4. continue leveling to 72/74
5. get new gear like iLvl200 head/nifflevars etc
6. queue
7. easily get ~2k rating
8. constantly get pwned by 2.1k+ teams
9. whine at forums about 70-74pvp balance
10. level to 85 and farm LFR/heroics
6. The 70 staying guy will be able to invite other 70 ppl to the team.
