Comments:From the skill data, the pioneers still do not have the heart of the ocean. In the thrilling supercar score, the pioneers can only add 5%, while the heart of the ocean is 6%, while the mileage score is 6%, in terms of firepower, the pioneer's skills can be reduced by 10% in the fight mode, while the heart of the ocean is reduced by 8%. In this regard, the pioneer has an advantage. However, the heart of the ocean can reach a maximum speed of 5.4 KM in the fight mode. This is not available to the pioneers, but the skill of the pioneers does not exist in the heart of the ocean. Therefore, the fire characteristics have their own advantages, but in general, the heart of the ocean is more powerful, but the pioneer is also a tough role, not worse than the heart of the ocean.
