3 boxing vs 5 boxing for PvP

[barney]

im playing 4 eles and when 1 dies i feel like there is no pressure left to kill a healer or well geared people, so with 5 eles the "pwnage" will be much better than 3. Five groundings and tremors are also better than 3.

I ran around in bg's with 4 shammies and it wasn't to bad. WSG was actually pretty decent for me since I could kill the flag carrier despite massive pressure. SotA was terrible though. AV was juicy since you could protect a tower like no other (TS everyone out the window lol).

I keep wanting to try running the 3v3 arena, but either am too lazy or worry about not having enough resilience.
