That's an issue with the user, not the system. NPC chat also does not accept. NPC chat skips chat until a Yes/No confirmation, then you must hit "Yes" or "Y".
It's what I was saying before, there shouldn't be a system that caters to incompetence or unwillingness to read. It affects everyone else's gameplay, especially for things like cubing which is done on a regular.
I like this proposed system. It helps reduce a ton of time and is a quality of life, which I feel Maplestory lacks a lot in.
I mentioned a dumbed-down solution in a recent post I made. I understand this may take awhile to implement the full solution, so implementing this system in steps would be great. As an example, Nexon can first implement a system which allows the user to reroll to a specific tier, rather than with specific line attributes.
As a second round of implementation, they can then look into the full solution provided here, which allows the user to select the lines they are most interested in.
I believe one thing to add in terms of cubes themselves. In Reboot worlds, cubes are often time-bound and are found under the "Use" tab, sometimes taking up multiple slots.
My suggestion would be - Remove the time-bound restriction for cubes, and create a system which allows you to accumulate cubes which would be present in this screen (similar to how you can accumulate legion coins and claim throughout any account that is part of your legion).
Example: Say I have 2 accounts. Account 1 runs through daily bosses and receives 50 Mystical cubes, 5 Hard cubes, and 2 Solid cubes - These are added to the stack. Account 2 runs through daily bosses, receiving a total of 35 Mystical cubes, and 2 Hard cubes.
When opening the proposed cube system mentioned above, the player is presented with a total number of cubes collected across all accounts and would be able to use them accordingly. In the example above, the player would see a total of 85 Mystical cubes, 7 Hard cubes, and 2 Solid cubes which can be used at their disposal on any character.
This eliminates the need to have cubes in your "Use" inventory, removes the time-bound nature of cubes, and removes the need to transfer cubes from character to character.
This is understandable. The only reason I highlighted hyper body is just to mention the number of "Decent" skills there are. I don't use it, as you mentioned, since bosses hit for percent health.
Pets are a good option, however not everyone has a pet that can auto buff, let alone on all their accounts.
We understand these nodes provide a skill for a set duration of 180 seconds which is across the board for "Decent" skills. Once attached to the V Matrix, this new decent skill can just append the newly added "Decent" skill's buff even with the leveling which adds + X all stats in some cases.
