The goldrush one by far:
- It was the first update (ofcourse there are bugs, dont blame valve)
- You had the unique situation of having only the same class in each server trying to get achievements and fail. Something youll never get later on again.
- New gamemode was added with a huge map
- Kritzcrieg (new tactic and uber targets that became usefull)
Also, the bad weapons of each update to me(over or underpowered):
Backburner - was a superweapon at that time, still overpowered by not nerfing it enough (W+M1 couse).
Sandvich - Useless. if there isnt a medic simply dont be a heavy as you wont survive anyway.
Bonk - quite useless, rarely any good situations as youll allways face sentry spam
Sandman - A stupid way to block ubers as it doesnt require risk and skill. And it even has a taunt kill... the normal bat deserved it more.
CnD - Camping spies... they were worse than W+M1 pyros as they somewhat slot waste.
Jarate - They get spammed just like the sandman except they hit much more often. They made pyros weaker except the W+M1 pyros as often you are dead before you can throw it.
Huntsman - As it is now... it can own most classes at 1 feet without any problems, a minimum range is required for it.
Razorback - it either should have its 20% speed loss or have the spy being able to swap weapons and attack with those instead after the stab. Now its too easy to survive against a spy with it which was allmost the only counter.
The ubersaw isnt overpowered. its stronger than its base weapon but its not overpowered as it does the same damage.
The blutsauger is overpowered but valve hasnt realized it yet by trying to kill some heavys with it on long range (as its not that hard), and then still... the medics that do that couse their team to lose anyway so they do get punished.
And in the next updates i except the following:
Food for the soldier... food=fail as has been proved twice
No good alternative for stickies and no nerf for them also... combined with demoman spam its even more fail.
Sentry spam
No very long stickyjump achievement (1000+ units) combined with killing someone with a bottle in it.
(yes, i can be whiny)
EDIT: a bit more info
