Two years ago Horn of Natar received huge buff which changed it from one of the most useless items into one of the best. There's still a lot of other items that are not good, can we have buffs to them to, so there's more useful choices in equipment?
Some ideas:
Shield and Breast-Plate Armor
The only bonus that these two provide are some hero fighting strength buffs. While it has some use within first week of the server, T2 and T3 of these are just joke, with biggest possible bonus being equivalent to less than 40 of the weakest troops.
What could help make these items useful would be for example additional 1%/3%/5% to Off/Def bonus (for example Off bonus to Breast-Plate and Def Bonus to Shield).
Chainmail Armor
Reduction of damage is cool, but it is clearly worse than reduction offered by Scale armor, and you lose improved regeneration of health to get bonus strength that at T3 is not even equivalent to 20 of the weakest troops.
Currently it is clear that there is no reason to get it instead of Scale armor.
I suggest buffing Chainmail to have better damage reduction than Scale armor for example by making it 6/8/10 points instead of current 3/4/5.
That way it would be interesting choice between the two.
Spy Glass
Theoretically it is incredibly useful as it forces enemies to send bigger fake attacks. Unfortunately everyone will just send bigger fake attacks without caring whether you have spy glass or not, so in reality it is completely useless.
What can be done is to give hero option to join scouting, and for example increase both offensive and defensive power of your scouts by 10%/20%/30%.
Pouch
Maybe it has some use at the beginning of the server, but considering how farming is done, and that it is impossible to have crannies for some significant amount of resources, it is not very useful.
What could help this item a little would be some change to plunder bonus.
For example it could also increase number of treasures stolen when treasury is not destroyed.
