Hi, lets jump to the list.
Game Design problems:
- Single leveling path
- Restrictions for building a character
- Too many mandatory content or lack of freedom
- Money TP/Gold stuffs that unbalance or broke the game in any way
- Overpowered or unbalanced classes, skills, combos, itens and etc…
- Lack of information and borring contest for early game
- Too many grind and time loss in the mid game (200 hours or more)
- Lack of content for late game
- No immersion, like changes of things on the fly (Class/Stats resets and similars)
- Too many restrictions on player to player interactions like parties, trade and quests
- Extreme and hardcore dead penalties
- AFK stuffs that affects gameplay
- Repetitive and boring content
- No need for strategy or too much easy game experience
- Very expensive pay to play or monthly payment
Art and Development problems:
- Unsolved exploits and bugs
- Massive and uncontrolled number of bots and RMT
- Bad GPU Otimization / FPS drops
- Poor art design
PVP:
- Unbalanced PVP/GVG
- Lack of PVP content and arenas
- Lack of updates and changes on meta
- Lack of e-sports content like tournaments and leagues
Response or interaction problems:
- Lag, delays, disconnections and network problems
- Bad designed controllers and input interaction
Community:
- Big amount of annoying or just rude players
- Lack of support
- Lack of moderation / GM speaking around with people on forum or in game
- Lack of events and community interaction
- Lack of information of any kind
From this list I made my TOP 5 of complains who can cause the greatest impact.
The TOP 5:
5 - Lack of content for late game
4 - Lack of PVP content and arenas
3 - Too many grind and time loss in the mid game (200 hours or more)
2 - Lag, delays, disconnections and network problems
1 - Unsolved exploits and bugs
The list was obtained by simple searching the complains of players on Steam, MMO communities and foruns listed on google.
In ITOS we have almost all those problems, now i see why people have stopped playing this game.
