hi again! what about when u level up u get 1 talent point.
press n to open the skill tree there is 3 different talents tree 1 strenght, 2 agility 3. stamina

why not have spell books that u can find in strongholds like *book of fire* throw fire ball
*book of ice* stuns the enemy.
zombies with armor (leather, iron, gold and chainmail)
skeleton with new arrows (fire arrows)
wolf (ride able)
enderman teleporting creeper or zombie or skeleton.

then minecraft gonna really fun too or more fun xD!

if u think this is good idea please comment and recommend
but if u thing this is not good comment and say your opinion please. :D
