I know that many people post ideas for supercell to read but I thought I'd give it a shot. I have a problem with upgrading my heroes because I need them for war. And many people want a new hero (although I hear supercell didnt approve and dont plan on making a new hero). But I think I found a solution:
1. Total of 3 heroes but player can only choose two to use in battle (that way we can upgrade the third hero without worrying).
2. Wizard / Mage hero: Old Gandalf looking hero that uses a staff, wand etc for short range shots for both air and land troops. (because BK doesnt hit air troops and he just stands there like an idiot while the dragon is roasting him).
3. Witch Hero that throws "potion bottles" long range (as long as the AQ) and when the bottle breaks, skeletons come out and start attacking. If one skeleton dies, she can throw another bottle for that 1 to come back.
4. Lvl 6 Golem - This is an over kill because Golems take forever to die but I figured a new golem that looks like a lava hound would fit the theme of TH10. Have lava drops come out of him and hit the floor. It would look cool.
5. Let us choose who can be in the Clan Wars. Even if we have 30 players in the clan, but only 10 want to battle, we have an option to have 10v10 CW. And if supercell doesnt want that, cool but let us at least pick who we want to war. For example if we have 14 players in our clan, that would mean our war will be 10v10. But sometimes noobs, or someone upgrading spell factories or heroes dont want to war have higher trophies than the heavy hitters and we end up kicking them and sending invites back. Some people get offended and never come back. WAHHHHHHHH
Anyway, what do you guys think? Again, I know this forum probably gets bombarded by 300,000 posts about new ideas. So I apologize for being the 300,001 post.
