NEW TROOP IDEA>SHIP(raft): so we can finally use water!

RAFTS!!!
BASIC BARRACKS UNIT level 7

COST: 200 elixer
HP: 50
HOUSING SPACE: 3
BUILDING TIME: 2 minutes
DPS: 0
SPEED: 10 (they stay on the water so not really important but still needed)

DESCRIPTION: This unit can carry 5 housing space, but is deployed only in water.
Basically every raft you build allows you 2 extra housing space.
Once built, these would go to the water.
Other units built would go to the barracks first, and to the rafts after the barracks are full.
It would take the troops hardly any time to unload and the defenses would shoot the rafts until they are off.

pros: lots of extra housing space
cons: only deployed on water, ergo, not much choice in strategic placement
takes time to build before building other troops

Level 2 upgrade: cost+100 DPS+10 HP+10 can now attack anywhere on land but attack nearest building first
level 3 upgrade: cost+100 DPS+5 HP+10
level 4 upgrade: cost+100 DPS+5 HP+10
level 5 upgrade: cost+100 DPS+5 Housing space+1

Let me know what you think! I know, not very exciting troop. Perhaps overpowered, but takes time and elixir. Maybe make a water building and have this be an option. I definitely think they should find a way to use the water though.

What should I build next? Mermaids? Lochness? Thanks for reading!
