Well.. 4th dan rankers were very nice in your country. Mr. Reyes, Ms. Macapawa(probably 5th dan now..), and Mr. Buenaseda were all good. Maybe your teacher is not one of them..
First of all, you must know that some teachers extremely stick to only one style, one method, one ..... They didn't allow any personal style. And they think it's their duty to make the students like them. I even heard that some teachers correct the posture of fingers inch by inch. Aikido is 'The ONE and ONLY Way of Harmony' to them. Well.. it might be common in Japanese martial arts.
However, IT'S OK as long as his/her students are good. IMHO, good teachers are judged by his/her students. If you can't see any noticeable progress from the beginners or yourself for two years, your teacher might be wrong at teaching though still he may be a good aikidoka.
IMHO again, everybody can be a good aikidoka but only a few can be a good teacher. If you have the good teacher, you're lucky. If not, don't worry. There are so many students like you. Now your journey to the good teacher is just begun! Good luck!
