Well you can argue that he have been buffed indirectly and I agree on it, but he still pretty much the same, the only difference is that before we had heroes that would do better without many cards. No whale needs Jacques and that's exactly what I said some posts ago to the person who made this topic.
No the buffs are completly different its not about "without jacques i can kill a garrison faster/easier". It completly changes EVERYTHING.
What happens if you attack a golden garrison with bronze without jacques? Nothing will happen. Garrison will lose maybe 1-2 units (not squads). If you attack with silver+gold you probably will kill it, but you will have also losses. If you dont put catapults in your setup you will probably die due to the fact, that the walled units alone will kill all of your setup at the end.
With jacque its totally and completly different. Because jacques is so insanly fast, he can burst down SQUADS not just units in the first few seconds while bronze is tanking. Your risk is exactly zero. You dont risk. Since jacques is a siege weapon as well you dont need catapults.
The difference is: without jacques you have to risk your gold and silver, which is greatly limited in amounts, you cant hit 10 times with your silver/gold. But bronze isnt limited, you can attack 20 times with bronze without risk and NO garrison will survive that.
And its not true that jacques didnt change. Free XP + Cards + crafting Equip + the change to his ammo capacity made him what he is.
His biggest source of dmg is his level (basic attack) and the multiplicators might and ability points, which are now extremly common and easy to get.
