I started playing from the start and advance quite a bit, with arena level at 109 and at level 70. Now I see that the latest updates have decreased the amount of HP that the arena monsters were supposed to get and other changes. Were these changes retroactive? If not, I'd like to be able to start over again from the beginning because it takes almose 2+ minutes just to kill one monster now in the arena and leveling up the sword doesn't help that much at all. 117K damage per swing while the monster have ...

Why after 10 monster kill around 200lvl arena they got +1,3 milion HP than after next 10 tehy got +1,6M hp. I need 74,7k money to upgrade sword and I get only 12k DMG but too get money for this I have to kill around 35-40 monsters. For my 12-15k DMG thet get 5-6M HP thats make this game so hard,bad,grindy and boring. Will it change or this is on purpose?...

I notice when you buy or upgrade anything the game will lock up slightly, now that i'm getting closer to the end of game, the freezing is like 2-5 seconds per click... Just trying to upgrade my sword 10-20 times takes roughly 1-2 mins, which isn't so bad but it's really adding up, just clicking to upgrade idle time takes roughly 5-10 seconds per click, takes forever to upgrade anything....
