Just got to level 80? Buy level 79 armor and weapons

I had a look at the difference and it's astounding. Here's a table for comparison between level 80 and level 79 Medium Traveler's gear on the Trade Post.

Armor Piece	Stat	Level 80 Stats	Level 79 Stats	Difference
Head	Defense	86	84	2
	Power	28	28	0
	Condition Damage	28	28	0
	MF	3	3	0
Shoulder	Defense	86	84	2

	CD	21	21	0
	MF	3	3	0
Chest	Defense	278	273	5
	Power	64	62	2
	CD	64	62	2
	MF	3	3	0
Leg	Defense	193	189	4
	Power	42	42	0
	CD	42	42	0
	MF	3	3	0
Foot	Defense	139	137	2
	Power	21	21	0
	CD	21	21	0
	MF	3	3	0
Total	Defense: 15	Power, CD: 2	MF: 0	Saving: Just under 6g

Each level 80 piece is over 1 gold, and each level 79 piece is under 50s, maximum.
Ideally you want to use this gear until you can craft your own level 80 armor!
