i'd rather make warleader a battlecry, so it does not snowball as much when being pulled out by finja tbh

This thread is hilarious. You're nerfing cards that are far from broken because they're just now seeing play? How long have you played hearthstone?

All terrible suggestions. 
Also HS is in the best state it's been for years, no need to change anything what-so-ever. 

"God DAMN IT, Hydrologist gave him ANOTHER ICE BLOCK."

The only right one is shadowstep. Dread corsair (as if pirate warrior was strong because of him) is useless, warleader is a buff, and hydrologist...ahahaha

Maybe Shadowstep cost 1 but reduce cost by 3. Same net result for later game larger minions, but tone down the novice engineer, swashburglar, and 1 mana 5/5 charge shenanigans.

I believe that non of those cards are problematic, if u going to nerf u need to nerf a card like Ice Block, and the best way to do that is Give imunne for you opponent on you next turn, so after i pop you block, the mage cant kill the enemy right away, beside that i believe u buffed warleader since health for aura effect is way better then attack, and Hydrologist is just a dark pedler that get u a secret and is not that powerfull, and paladin need the early game, if u could change something on the card is take the murloc tribe on it so it doesnt get sinergy with murlocs

Instead of asking them to make the game easier for you personally by destroying perfectly legitimate play styles, you might want to consider improving your skills so that these cards are not so bothersome when you encounter them.

Probably the only card I'd want to nerf in the entire game right now is Fiery War Axe, giving it "Can't attack heroes."
