I really think that you should change the axe and shovel to eff 10 in the nstar shop because with a eff 7 its ligit no diffrent then a eff 5 and with a eff 10 you could break things instantly well flying which really is the LEAST you could do you a 500k tool. Same with the axe theres no point in getting it because it dose nothing better then the eff 5 with a eff 10 axe you can break wood instantly which I really dont see causeing the economy to crash because someone got some wood quickly. The pick already breaks thing instantly so I dont see why you can do this with the axe.
if Eff 5 and Eff 7 are identical, why would Eff 10 be any faster. It seems to me that there is some cap for break speed on certain blocks, and the wood/shovel blocks are up against it at Eff5.
I am not sure if andrew knows about the issue with eff7 axe/shovel. In my testing, the only time I've found them to be faster is while jumping or flying.
As a owner of EFF7 AXE, YES! i agree with this. It should really change. If you guy take a look for "Speed and Durability" chart in below link: http://minecraft.gamepedia.com/Axe currently EFF7 AXE is only destroying blocks instantly that's below "0.3 sec(dia tool standard)" which is currently, only bookshelves.. above 0.4 second it's still almost same speed as eff5, and spending 1500 nstars to get eff7 axe that only has better usage of destroying bookshelves? hell no. Honestly, before I get eff7 axe, i thought eff7 will break most of the wood type of blocks instantly, and that's why I got it. And I didn't even know about that chart link. I was soooo disappointed that i figured out that. Actually, I was shocked.. Now I really kinda regret getting this axe. I really hope this axe and shovel would change to something like eff10, or any lvl of efficiency that can break most of the wood type of blocks(0.4 sec or 0.5 sec type of blocks in that chart link) instantly and for those of players who already got eff7 axe or shovel, it would be nice if andrew change it to eff10 for us after the change. And as a owner of eff7 axe, people who is planning to get it, by assuming that eff7 axe would break wood planks or wood logs instantly, NO! DON'T GET IT!!. It doesn't break it instantly, so please don't make mistake like me and regret it.
As for the people that got the eff 7 before this chnages (hopefully it dose ) I think that the people who boght one should be able to trade it in by pming Andrew and supplying evidence you have a eff 7.
