I have many ideas for high level benefits... this way, players will have a reason to want high levels instead of many complaining about how level is useless.
Idea 1: Every time you level up, you are granted a gem amount equal to the level you have leveled up to. Previous levels will not be counted to avoid large amounts of gems being gifted at once. Example: Leveling up to level 63 grants 63 gems as a leveling reward.
Idea 2: Each level grants +0.01% statistic bonus for the following...
-Troop Attack Damage, HP, Movement Speed, Attack Speed
-Spell Damage, Effect, Duration
-Defense Attack Damage, Blast Radius, HP, Attack Speed
This does not effect clan castle troops, since they were given to you. If you do give someone else CC troops, the troops you gave them will have your bonus statistics, not theirs.
Idea 3: Levels grant daily bonuses... 5% of the level number is given, so if you are level 100, you gain 5 gems per day. Always rounds down... half a gem is worth nothing, 5/6 of a gem is worth nothing... etc.
Idea 4: New decorations. There should be new decorations unlocked at levels 100, 125, 150, 175, and 200.
Idea 5: You can unlock a new skin for your Clash of Clans village (similar to Battle Beach skins for villages) at level 100, but it costs 500 gems. Visible by attackers
Idea 6: Levels can unlock special effects in-game attacking and defending upon reaching certain levels.
Idea 7: Stolen resources are increased by 5% of your level. If you are level 100 and raid 100k gold and elixir, and 1000 dark elixir, then you will end up having 105k gold and elixir, and 1050 dark elixir. The defender does not lose the resource bonus. This will increase the loot economy to those whiners who won't shut-up about horrible loot. Collected resources are also boosted by 5% of your level.
Idea 8: A new army camp can be unlocked, and 10% of your level will decide the amount of troop capacity. Level 100 = 10 troops, level 57 = 5 troops, etc. Always rounds down.
To sum it up...
Idea 1: Gems every level up
Idea 2: Grants buffs for troops and defense
Idea 3: Grants daily bonuses in gems
Idea 4: Unlocks new decorations
Idea 5: Skins for your village
Idea 6: Special effects
Idea 7: Increased resource income from raiding, mines, collectors, and drills.
Idea 8: More troop capacity
Vote for whatever idea you think would be great to have in Clash of Clans... Why are there donating clans if they're going to level up and just have the title? Good question... Everyone's looking forward to this.
