I hope this question doesn't sound superfluous, but I have wanted to know if this possibility existed.

since I have learned Esperanto a year ago, I have noticed that people tend to rely on "esti" too much. Instead of using the verb accusative case. I prefer to be more specific in verbs rather than using "to be."

Some people also use to be to describe nouns like "Tio estas bona." Instead of "Tion bonas." I know both are acceptable and grammatically correct but some conversations get saturated with thousands of esti. It seems increased use of rare verbs adds more depth to conversations.

Is it possible to never use esti while still being specific?

Why always use esti when a verb can easily describe that the object already is "being."

I'm not a grammatical wizard and my grasp of Esperanto is not very strong but I was curious. It seems Russians might have some trouble with the verb to be since it's not present in the language. I remember reading something about not using the article but never saw anything about this.

*Tion bonas is incorrect. Perhaps you meant "tio bonas", without an accusative ending.

In some, but not all, cases, using an adjective in verb form conveys a slightly different meaning than simply saying "estas [adjective]", particularly if you are talking about a state that can change.

In short, if you want to talk with never using "estas" with an adjective, you can. You will sound a little unusual but that's your decision to make, how you want to sound, and individuals certainly do use it to greater or lesser degrees.
