Good:
-Addons
-Stackable Items
-Items-with-few-weight
-Hunting Task
-More detaills
-Teamhunts
-More monsters and bosses
-More weapons (assassin star, spears, more axes, etc.)
-Level requirements on weapons (not everybody can walk with a sca nomore)
-Support sites (wikia/tibia-stats)
-More kinds of potions and runes.
-Bigger huntspots, for higher levels.
Bad:
-Anti-bot measures (isn't it easier to make it impossible to login with bots insteed of banning whole tibia?)
-Hotkey aim
-Yalahar
-Burst arrows can't be used nomore by mages.
-Wands/rods
-Deleting all GMS ??
-Voc requirements on weapons/armors/legs (mpa can't be carried by mages)
-Botting!!!
Hope they will do something like this into a next update:
It should be cool if having an addon will mean something.. So if you got sniper gloves (hunter addon), than you can shoot + 1 SQM distance, if you the cape, you are 1% harder to hit or so.
