Your Suggestion: Chat interface change to where each type of chat is in their own tab. This would allow us to check easier if something is said in alliance chat.
How it can help: Easier flow of checking on alliance chat and other chat sections.
How it may not help: Someone could not see something in All Chat window while tabbed into Alliance chat window.
Your Suggestion: Allow us to know how many skills a hero can have total. Like how Monty can only have 1 skill, while some of my normals have 2 skills, and some of the epic heroes can only have 3.
How it can help: Know when you can use a book on a hero or not that it would replace the skill since slots are actually full.
How it may not help: Don't see how it wouldn't, unless maybe some heroes wouldn't get used as much due to having less slots.
Your Suggestion: Improve the instances to give Sire XP as well. Since instances are limited to the amount of sire vitality you have and that improves with Sire level. Then allowing that to give more sire xp would be nice.
How it can help: Easier flow of leveling other than daily quests.
How it may not help: Crown buyers would be able to buy vitality potions to continuously level.
These are all great. Something like the chat interface in Call of Gods would be ideal I think, with the tabs between main chat and alliance chat (and one for all the immeasurable trade and system spam that makes it impossible to read anything else)
Your Suggestion: Aditional/clarified sections in the mail box. Inbox for composed mail or alerts such as quest spawns or trade notifications, one for battle reports, one specifically to hold items gained- this could also go straight to the main inbox.
How it can help: It removes the clutter and helps reduce some of the superfluous need for clicking. By changing the organization and removing superfluous functions it becomes more efficient and less confusing. There is already enough clicking without having to search through 20+ pages of battle reports to collect loot or find a certain message.
How it may not help: Maybe some people like the jumbled up clutter of everything being stuffed into one box by default. A possible disadvantage would be people forgetting to check their mail, but that can be fixed by having the text labeling each tab glow yellow when there is a new message in it.
