First of all I wanted to say a big thank you to the whole dev team and everyone else working Terraria. In addition a big shoutout to all those Terraria content creators and the community itself which made all of this big and free content available in the first place with their continuous support and love. I'm so freaking hyped and can't wait any longer to finally touch the update myself.
Now regarding many of the changes mentioned here in the changelog:
I can unterstand, that many people will get upset with the various nerfs of cheesy strats and exploits that have been long around. I for myself always did the crate stacking before hardmode, not because of the difficulty but the random evil biome spread when breaking altars. (
Remember that you'll still be able to prepare safe fishing spots, boxes etc. and fish those crates once you entered hardmode. There's still no need for breaking altars this way if you want to get your hands on the new ores) Or destroying the Destroyers whole career with the Daedalus Stormbow.
But these things alongside the reaver shark weren't intended in the way we used them. Terraria is heavingly focusing on mining and gear progression and skipping whole pre-hardmode with some effort in fishing isn't the way the game should be played. Of course we
loved the ways to help us getting along easier but I really appreciate the idea of utilizing more kind of things the game offers instead of always going the meta just because it's too good to miss.
In case of the balancing of weapons and stuff I think future updates as said in the thread could help with some issues here. But if you think "Oh gosh they ruined the thing I always used" just try thinking if this wasn't the case because it was kind of op in some ways. My personal hope is that all methods of playing the game will be more sticking together in their effectiveness with less over- or underpowered parts in the top and bottom.
Some words especially to summoner class because some are already calling it dead.

I love being a summoner and through all of it I see more buffs than nerfs. We'll get plenty of more weapon options (especially starter weapons), stardust armor gets a huge buff (who actually used the guardian manually?), we get a whole new weapon class which will surely scale with your summoning damage, the extra immunity frame function reduces the feeling of being some kind of hybrid class (along with our own weapons). I really can't stand the point summoner would be dead, I'm more happy and looking forward to play this class than I've ever been before.
tl;dr: Nerfing cheesy strats is good for the game itself, balancing will continue after 1.4 and devs, please don't mind the people seeing all this and just point out some things they're bothered of, you won' be able to satisty everyone (and you know that).
PS: English isn't my native language so I'm sorry if this should be bad to read
