Microtransactions and DLC ? I do not think Re-logic wants to commit reputation and financial suicide that soon.
Durability and needs ? I don't see why they should be implemented either. Mechanics do not support them, and devs see it too.
What am i afraid of ? MMO-ification.
Luck-based items or missions : We got enough RNG already, we don't need even more. I already talked about it
here.
Sponge bosses : I'm afraid some bosses may become this. No mechanics, just hit until it dies. So fun.
Mechanics intended on co-op without scaling : Moon event waves. More difficulty = more mobs. Yay.
Senseless grinding : I want new items from discovery and chests, not by doing the same thing over and over and over again. I have MMOs and Diablo for that.
Power creep : I don't want 1.3 tier just like 1.2 which added items that were strictly better than same-tier existing ones (Ores, Crimson, mini-biomes items), only based on luck for acquisition.
Dead balance : 1.1 killed the economy, 1.2 killed the balance. End-game PvP is dead, and so is gear variety. Just like WoW or League, do this or die. Also no power = rarity BS please.
