The stars represent quality. The highest is 3 stars and the lowest is no stars. The general attributes with stars are higher than those without stars. The weight and performance will also be improved. And having stars is not necessarily better than nothing.

For example, SE engines with stars must have relatively powerful performance, SE attack is relatively high, and the load capacity of the engine is greatly increased..

It should be noted that some star ratings are fixed. It is impossible to obtain other stars without gold fingers. For example, the star rating of T Tyrannosaurus is constant. If you use old gold to modify a 3-star T Tyrannosaurus, then T Tyrannosaurus will be the strongest engine. If you do not change it, then T Tyrannosaurus will be the strongest engine. Dragon Qian 5 is barely advanced.

Although the main gun and secondary battery can also increase the attack power, they are not commonly used. The star rating does not matter, especially the main gun is usually installed with the lightest one for firing. Special shells with stars are heavier, so they are useless at this time. Those without stars are better.

The C device adds defense, and the defense is useless before the armor piece is gone, and the armor piece is gone. It only slightly reduces the chance of damage to oneself, and does not change the performance. Therefore, the weight of high star rating is heavy, but it is not necessary. Therefore, the low star rating is better

In addition, most of the star rating is obtained randomly. Yes, so when you brush some equipment, you have to brush it repeatedly to get better things. If you have 1 item per week, you usually save it and try it repeatedly to get the star rating you want...
