When it comes to Warframe, there is no lack of content to be had. However, some players may feel that the game could use more mod slots.
This is because there are a limited number of mods that can be equipped at any one time.
As such, it may be useful for Warframe developers to consider adding more mod slots to the game. Doing so would allow players to equip more powerful mods, and would also make the game more accommodating for a wider variety of player styles.
In conclusion, adding more mod slots would benefit Warframe as a whole, and would likely please many players.
