Features I have seen in similar games

I've been playing Clash of Clans, and similar games for quite some time (4+ years counting greed for glory and backyard monsters) and there are a lot of features i have seen that make the quite a bit more enjoyable, and a lot of features I think would make the game more enjoyable.

So lets start with features i have seen in similar games that i think would be a great addition to Clash of Clans

Player Clan History
One of the most frustrating things currently in Clash of Clans are Clan hoppers. Everyone knows what I'm talking about. You get someone who wants to join your clan, and then the next day, mid war or after they get a full CC then leave. In games i have played previously i have seen a feature that documents how many clans someone has been in, and how long they were in it. When a player would apply for a clan, you could check their profile and see if they have jumped 50 clans in the past month, or if they have stuck in one or two clans for a month each.

Player Activity
Currently the only way to check a players activity is to monitor their base and see if they have logged on recently by guessing if their base has been destroyed/rebuilt. In other games i have seen many ways of documenting a players activity. The best way i have seen was a small circle next to the players name (in clan menu) if the player has logged on within 24 hours the circle is green, if the player has logged on 24-72 hours the circle is yellow, anything above that the circle is red showing the player has been inactive for over 3 days. This feature would be really convenient for clan leaders to be able to distinguish who their active players are and are not merely at a glance.

Dueling
How do you know if your base set up has a good defense? how do you test out a new attack without putting your elixir and trophies on the line? In previous games i saw a feature where you may duel someone in your clan(once every 24 hours) and they would lose no resources or trophies, and you would not lose your troops after the duel was complete. This allowed players to test each others strategies.

Potion Dumping
We currently have the feature to remove troops from our barracks, yet sometimes you need to remove a potion from your spell factory. Please add the feature to remove potions from our spell factory.


This is currently all the features I can think of, but i'll be editing this post to add things as i remember them.

Clan Builder
In previous games I have seen a "clan builder" You get one of these bad boys, and you may assist someone in your clan with one of their buildings, thus cutting the upgrade time in half. The builder stays with that building until it is finished being upgraded, then you may assign it to someone else in your clan. (only one clan builder per building being upgraded)

yes most of these changes would greatly enhance game play... im in!!

Ideas 1, 2 and 4 are great, sadly 3 and 5 are ruled out. However I would like to see them all in game.

The first one could be implemented, but has no use for me or my clan because we enjoy hoppers (adds to our donate count and gives some xp, we aren't donating for a reason other than because we want to donate). So I'm in on that.

The second could be problematic. A very similar feature is ruled out. (online indicators), but it could be implemented because it is not directly ruled out. However, please note, this could cause some lag. However, 24 hours is a long time in which we don't know when they were online. This could illimate the reason online indicators are ruled out (privacy issues), but also add unnecessary drama and misunderstandings.

The third will not work. It is ruled out because you could edit your base to act like one of your clan war enemy's base and practice on it untill you get a foolproof plan.

The fourth would be a nice feature. I'm in.

The fifth is ruled out. Cutting building time means less gems for Supercell, which means less money, less profit and less development.
