This was discussed in one of the earlier threads. Basically, in the alpha (subject the change), there was gear tagged as "Heavy Armour". Only lancers and Marauders could wear it. It wasn't really out of place though, because Glads tank using a shield, not using high defense gear. It appeared (at least in the alpha version), that Glads were supposed to use a shield, PUGs had better evasion and abilities that could be used on evading attacks, and Lancers/Marauders had access to higher defense gear.
Clearly there are pics of Glads in what appears to be heavy armour, but we dont know if:
A.) It just looks like heavy armour, but isn't
B.) Gear could have changed completely from the alpha > beta
C.) Gladiator might get the ability to wear heavier stuff at higher levels
In regards to A. When this came up in the previous threads, I posted pics of my PUG wearing gloves that were classed as medium armour, but looked like they were plate armour.
Until we see some higher level gear in the alpha (which means higher level crafters or possibly high level leve rewards), we don't know for sure.
The "desync" was a bug in the first few weeks of the alpha. Basically the game lost you sometimes when you zoned. You were still logged in, you could chat to other players, but you couldn't zone again, use teleports, or open doors. Mobs wouldn't load, nor would NPCs. You could explore the zone you were in, but had to relog to fix it.
On top of the login server issues on Thursdays test, a bunch or people were reporting that the "desync" was happening again, but based on what SE have said since, hopefully they will have it fixed.
